.HL1 Introduction
Standard DECsystem 10 software provides a powerful but complex command interface.
Novice terminal users lose much time through an unforgiving command decoder and the expert resents
the verbosity of the average command string. Although the concise command language (C.C.L) does allow
many simplifications to system commands, new commands may not readily be defined.
.s
With MIC a user may create a new command simply by writing any desired sequence
of monitor and user mode commands in a disk file. To cause the command to be obeyed
.in do
the user types to monitor the filename preceded by the forward slash character "/".
.else do
the user types to monitor the filename preceded by the "DO" command.
.ei do
.s
E.g.
.S
If the file DTASAV.MIC contains the text-
.s.nf
.R PIP
*DTAX:/X/B=FRED.TXT
*_^C
.DIR DTAX:
.s
the user could obey the command file thus-
.s
.in do
./DTASAV
.else do
_.DO DTASAV
.ei do
.R PIP
*DTAX:/X/B=FRED.TXT
*_^C
.DIR DTAX:
.s.f
In this sequence of commands only the first line of the "MIC command" was typed by the user.
If the user often required this sequence of commands the command macro DTASAV.MIC would save
a considerable amount of typing.
.s
To allow more generalised commands to be constructed a MIC command may have parameters:
.s
The command macro DTASAV.MIC would be made more useful if the file contained the text-
.s.nf
.R PIP
*DTA'A:/X/B='B
*_^C
.DIR DTA'A:
.s.f
.tp 15
The rules for parameter substitution are simple.
When 'A is encountered in the command file the first parameter is substituted. The first
parameter in the macro DTASAV is the dectape number, the second parameter is the file name
to be transferred.
Up to 26 user parameters are allowed ('A to 'Z).
To write the file PETE.MAC to DTA3 the command would be:-
.s
.in do
./DTASAV 3,PETE.MAC
.else do
_.DO DTASAV 3,PETE.MAC
.ei do
.s
The parameters to a MIC command are separated by commas. (See also section 2.)
.s
The command file may be of any
size and is typed by MIC line by line exactly as if the user had typed it. MIC will
only type a line when the job requires input. To stop MIC typein the user must type control C.
.s
Using the above information a user can easily make his own commands.
Additional facilities in MIC are provided to allow:-
.s
1. Parameters to be manipulated during the processing of a MIC command.
.s
2. Conditional branching within the command macro.
.s
3. Detecting and processing error conditions.
.s2
.nt
MIC command files may themselves contain MIC commands. In
this case the "nested processes" each have their own parameters but
inner processes may access the parameters in an outer process. This
is described later.
.en
.tp 30
.HL1 Introducing a MIC Command
.index Command File
To cause a MIC macro command file to be obeyed a monitor command of the following form is
used:-
.s
.in do
./<Standard device-file specification> <parameter list>
.else do
_.DO <Standard device-file specification> <parameter list>
.ei do
.s
.in do
The first argument to the "/" command specifies the command file to be obeyed,
.else do
The first argument to the "DO" command specifies the command file to be obeyed,
.ei do
in the form DEV:FILENAME.EXT[PPN]
If the user does not specify where the command file is held, his own
area is searched first followed by the ersatz device MIC (1).
.footnote 7
(1) The exact order of search can be varied by the system administrator
but by default is:-
.nf.s
DSK:FILE.MIC [PROJECT,PROGRAMMER]
DSK:FILE.MIC [PROJECT,PROGRAMMER,MIC]
DSK:FILE.MIC [PROJECT,1]
MIC:FILE.MIC
.f
.end footnote
The default extension for the MACRO file is "MIC".
The full default filespec is DSK:MIC.MIC in the user's own area.
Sub-file directories are supported by MIC.
.s
The parameter list follows
after a separator character (space or tab). Parameters are separated by
commas. All brackets in the parameter list must match. A comma between matched brackets
does not separate parameters. Outer matching < and > brackets are removed before the
parameter is substituted.
.s
E.g.
.s
.in do
./C[105,13] TWO
.else do
_.DO C[105,13] TWO
.ei do
.s
MIC macro file is C.MIC in area [105,13].
.br
'A would substitute as TWO.
.s
.in do
./C A[105,13],3
.else do
.DO C A[105,13],3
.ei do
.s
MIC macro file is "C.MIC" on the user's own area or "MIC".
.br
'A would substitute as A[105,13].
.br
'B would substitute as 3.
.S
.if do
.nt
The original versions of MIC used the "/" command, not the "DO" command,
and this is still used on some sites, and may be referred to in some
documentation.
.en
.ei do
.in do
.nt
A MIC macro command may also be introduced by using the "DO" command,
.s
e.g.
.S
_.DO C[105,13] TWO
.INDEX DO Command.
.s.f
N.B.##On other DEC-10 installations the DO command may be the
only form available.

.HL1 Constructing MIC macro command files
.s
.index Command File
A MIC file may contain any ASCII text with or without line numbers.
This text is taken line-by-line and typed on the user's terminal as
though he had typed it.
To allow the user to write macros which are easy to read, leading spaces and tabs
are ignored. Thus the two lines:-
.s .nf
*/X/B=*.SAV
.S
and
.nf.S
*/X/B=*.SAV
.f.S
are equivalent.
.s
.index Line Numbers
.nt
1.##Existing "MULTIPROGRAMMING BATCH" control files may be used as
MIC command files.
.s
2.##On labelled lines, any space after the label terminator (the "::")
are treated in the same way.
.s
3.##The leading space feature is not compatible with batch control files.
.en
.tp40
.HL2 Special Characters
As in batch control files some characters are treated specially as the file is processed.
.index Special Characters
.s.nf
.ts 17,42
Character Position Meaning
.s
.index .(dot)
. at start of line Remaining text on this line
may only be typed to monitor
.s
.index *(asterisk)
* At start of line Remaining text on this line may
only be typed as program input.
.s
.index =(equals)
= At start of line Suppress carriage return at the
end of this line. Useful for
command macros containing DDT
and TECO commands.
.s
.index ;(semi-colon)
.index !(exclamation)
.index Comments
! or ; At start of line Treat line as a comment. Line is
.index SILENCE
displayed on the user Teletype
but not typed to the job.
.s
.index Control Characters
_^X Any Convert character "X" to control
X before it is typed.
.s
.index Parameter Substitution
'A Any Substitute parameter A.
.S2
If a special character is to be treated literally it must be repeated.
.s
E.g.
.s
''A will be typed as 'A and not cause the substitution of parameter A.
.S
.nt
1.##"!" overrides the silence condition, but the normal comment character ";" does not.
.s
2.##"_^C" or "_^A" do not have the same effect when typed by MIC,
as they would have if the user had typed them, in that they do not "CANCEL"
or "ABORT" the macro.
.s
3.##Lower case letters are converted to upper case in the "_^X" and
"'A" cases.
.en
.pg
.HL2 Labelled Lines
.index Labelled Lines
Any line in a command file may be labelled. A label may be of any length,
but only the first six characters are significant. Labels may be
constructed of any alphanumeric characters terminated by a double colon.
Labels can only occur at the start of a line.
.index Labels
.INDEX :: (double colon)
.s.nf
E.g.
.S
FRED::.DIR
.S
THISISALABEL:: .R PIP
.S
ANOTHER1::*/X/B=JIM.ALG
.S
.nt
1.##Labels which begin with a "%" character have the same special meanings
as in "Multi Programming Batch", see 4.2.1 .
.s
2.##Labels must always be in upper case.
.en
.HL2 Parameter Substitution
The construction 'X where X is an alphabetic character, causes the
contents of the appropriate parameter to be substituted.
.s
Nested parameter substitutions are allowed,
.s
E.g.
.s
'X may contain 'Y and so on to a maximum level of 8.
.Index % labels
.pg
.HL1 Commands derived from DECsystem-10 Multi-Program Batch
.Index BATCH Commands
.HL 2 GOTO/BACKTO Command
.Index GOTO Command
.Index BACKTO Command
As with batch control files a MIC command file may have some lines
labelled.
Using the MIC monitor style commands GOTO and BACKTO the
sequential processing of the MIC command may be interrupted.
The argument to the GOTO/BACKTO command is an identifier of one
to six alphanumeric characters which is used to indicate the
label in the MIC command file where processing is to resume.
.s
.Index Labels
The appropriate labels in the command file are delimited
.Index :: (double colon)
by :: and must be at the start of a line.
.s
E.g.
.s
FRED::.DIRECT
.s2
.Index %FIN
.nt
1.##That, if, when MIC is searching a command file for the first
occurrence of the required label, it comes across a "&%FIN" label, this
will satisfy the search and processing of the command file will be
resumed at that point.
.s
2.##As GOTO/BACKTO commands are interpreted by the MIC program they do
not destroy the user's core image.
.s
3.##The formats
.S
_.GO TO <label>
.s
and
.s
_.BACK TO <label>
.S
may be used, but these do destroy a user's core image.
.en
.pg
.HL2 ERROR/NOERROR Command
.Index ERROR
.Index NOERROR
As the MIC command file is processed an error may occur.
Often a message is displayed on the user Teletype preceded
by a question mark (?) character.
.INDEX ?
By using the error command
the user may specify which character is to be treated
as denoting an error condition when it is displayed at the start of a line.
.s
The argument to the error command is any single ASCII printing character.
.s
E.g.
.s
_.ERROR %
.br
_.ERROR ?
.s
If no argument is supplied to an ".ERROR" command a question mark (?)
is assumed.
.s
The command NOERROR is used to turn off error checking.
.HL 3 Error Processing
.br
.Index Error Processing
.s;
Error processing in MIC is similar to that of MULTIPROGRAMMING BATCH. If an error
is detected MIC will check if the next monitor command is an
"IF (ERROR)" or "IF (NOERROR)" command. If this is so, processing will
continue there, otherwise the command file is searched for a
.s
%CERR or a %FIN if the error occurred in a system program,
.s
.Index %CERR
or
.s
%ERR or a %FIN if the error occurred in a user program, before typein is
resumed. If this fails MIC will display on the user's Teletype
.INDEX %ERR
.INDEX %FIN
.s
[ABORT ON ERROR]
.INDEX [ABORT ON ERROR]
.s
and stop processing the MIC command file.
.nt
1.##The WHENEVER/ON command may be used to change this default processing
(see section 11).
.s;2.##If a "%" label is detected when we are not processing an error,
then the commands following that "%" label and up to the next
occurrence of a "%FIN" label will be ignored (cf. BATCH).
.en
.pg
.HL2 IF Command
.INDEX IF
.INDEX IF Command
The IF command is used to conditionally process a monitor command.
.nf.s
E.g.
.s
_.IF (ERROR) .GOTO EER5
.in do
_.IF (NOERROR) ./UPDATE 13
.else do
_.IF (NOERROR) .DO UPDATE 13
.ei do
.F.s
The monitor command is obeyed if the specified condition is true.
The alternatives MIC provides for the ERROR/NOERROR conditional are discussed
later.
.s
A batch control file called JOB1.CTL could be executed
at the user's Teletype using the command:-
.s
.in do
_./JOB1.CTL
.else do
_.DO JOB1.CTL
.ei do
.s
.nt
1.##Users who wish to use MIC in this way should note that the default
error status when a MIC command is executed at the teletype is
"NOERROR".
.s
2.##The commands "IF (ERROR)" AND "IF (NOERROR)" do not destroy the
user's core image.
.s
3.##"IF (ERROR)" "IF (NOERROR)" are compatible with Multi Programming Batch.
.en
.HL2 OPERATOR/NOOPERATOR Command
.Index OPERATOR Command
The Batch command "OPERATOR" is also used in MIC. Its operation is
described in section 7.1.
.pg
.HL2 SILENCE/REVIVE Command
.INDEX SILENCE Command
.INDEX REVIVE Command
These commands are used to suppress typeout
on the user teletype throughout an uninteresting sequence of commands.
.s
Another monitor level command may be placed on the same line as a SILENCE or REVIVE command (see section 14).
.s
E.g.
.s
_.REVIVE .DIR
.S2
This has the useful effect of reviving the tty output after the "DIR"
command has been typed. Thus the user sees only the output from
the command, not the command itself.
.s
N.B.
.Index SILENCE (protection code)
.index Protection Codes
A whole command file may be automatically silenced if the file is given the protection code
<2??>. This may be overridden in the command file by the ".REVIVE" command.
.HL2 PLEASE Command
.Index PLEASE Command
Unlike DECsystem-10 batch, this command is used to communicate
with the initiator of the MIC command. The argument is displayed
on the user's teletype regardless of the SILENCE/REVIVE switch.
.s
If the PLEASE command is terminated by an altmode, MIC typein
proceeds normally, otherwise typein is suspended by a [BREAK] until the user
types _^P or a MIC PROCEED command to proceed and [PROCEED] is displayed.
.INDEX [BREAK]
.INDEX _^P
.INDEX Control P
.INDEX [PROCEED]
.INDEX PROCEED Command
.s
E.g.
.s
_.PLEASE LOAD DECTAPE 345
.br
_.PLEASE THANKS$
.HL2 CHKPNT/REQUEUE Command
.INDEX CHKPNT
.index REQUEUE
The batch pseudo commands CHKPNT and REQUEUE are supported by MIC in the
sense that they are interpreted and discarded. MIC regards them as being
a form of comment and discards the line, though it will be displayed if
the user is not silenced.
.s;The user's core image is not affected.
.HL2 Others
In fact all batch pseudo-commands are legal monitor commands
when obeyed from a MIC command file. MIC extends the batch command
format (see section 6) and provides several new commands.
Users unfamiliar with DECsystem-10 batch facilities
should read DECsystem-10 BEGINNERS GUIDE TO MULTI-PROGRAM BATCH
for a fuller description of the batch commands.
.pg
.HL1 LET Command
.index LET Command
The general form of the MIC monitor command "LET" is-
.s
.LET <parameter name>=<expression>
.s
Decimal, Integer, Octal or string expressions may be used.
Users parameters to MIC command macro files are
held within MIC as ASCII strings.
.s
During the execution
of a MIC command macro the LET monitor command may be used to
change any of the parameters (A thro' Z).
.s
E.g.
.index Expression-string
.s
.LET C="THIS IS THE NEW PARAMETER C"
.s
After this command 'C in the MIC command file would cause the
substitution of the text-
.s
THIS IS THE NEW PARAMETER C
.s
In fact "THIS IS THE NEW PARAMETER C" is the simplest form
of a string expression. A more complicated command sequence
could be-
.s
.in do
_./TEST FRED,BAK
.else do
_.DO TEST FRED,BAK
.ei do
.br
_.LET Z=$A+"."+$B+"[105,113]"
.s
Dollar A ($A) is used as a reference to the string parameter A.
.Index Concatenation
Plus (+) is a simple concatenation operator.
After the LET
command the parameter Z would substitute as the text-
.nf.s
FRED.BAK[105,113]
.s
.nt
In LET statements which include a carriage return/line feed within
the string quotes MIC will display a "--" at the start of the new line.
.en
Simple integer expressions are allowed in the LET command-
.nf
.Index Expressions-integer
.s
E.g.
.s
_.LET B=3+C*3_^D-4/(A+B)
.f.s
In this example A B and C are used as references to the
value of the parameters when read as integers. If any referenced
parameter may not be read as an integer an error will result. The
operators + * / - _^ have the usual meaning and precedence.
Round brackets may be used to alter the usual precedence.
.pg
.HL2 Byte Subscripting for String Expressions
.index Byte Subscripting
.s
Often in the LET command it is required to construct new parameters.
The simple string expression has been extended to provide powerful character
subscripting facilities.
.s
The format for a simple subscripted string expression is:-
.s
$A.[<first subscript>,<second subscript>]
.s
Here A may be A-Z. The first subscript is used to specify the first parameter
in character <A> to be used in the subscripted string. The second subscript
specifies the length of the constructed string. Consider parameter <A>
to be a string numbered as follows-
.s3
.literal
1 2 3 4
---------------------------------
| F | I | R | S | T
----------------------------------
-n -n+1 -n+2 ...
null
n-2 n-1 n char
---------------------------------
L | A | S | T | |
-------------------------------
-4 -3 -2 -1
.end literal
.s2
.c;Fig 1 Character string N bytes long
.s
If the second subscript is omitted the length of the constructed string
defaults to one character.
.s
.pg
E.g.
.s
If the parameter A contained the text ABCDEF
.nf.s
Command Result after command
.s
.ts 33
_.LET B=$A.[1] A
_.LET B=$A.[2] B
_.LET B=$A.[-1] F
_.LET B=$A.[99] <null>
.s.f
If the first subscript is out of range a null string is constructed.
Extending the previous example for two subscripts
.s.f
_.LET B=$A.[1,2] AB
.br
_.LET B=$A.[3,2] CD
.s
Subscripts themselves may be string expressions-
.s
_.LET B=$A.["AB","F"] CDE
.s
This construction means copy the string in parameter A between
the text AB and F to parameter B.
.s
Repeated subscripts are allowed-
.s
.LET B="DSK:FILE.EXT[105,113]"
.br
.LET B=$B.[":","."].[,"["] FILE
.s
This construction means truncate the object string in parameter B
after the character ":" at the character "." or the character "[".
.S2
.ts 8,16,24,32,40,48,56,64,72
.HL2 Multiple LET Statements
.index Multiple LET Statements
.S
Several LET assignments may follow the one "LET" statement by
terminating every assignment except the last, by a comma.
.s
E.g.
.s
.LET A=1+2,C=$B.[1,2],D=C+"ABCDE"
.pg
.HL2 Parameters in Outer Processes
.index Parameters in Outer Processes
Parameters in an outer MIC process may be referenced in the inner process
by following the parameter by a digit corresponding to the process level - the current process is regarded as being level 0, the first surrounding
process is level 1 and so on.
.s
Thus:-
.s
.index Outer Processes
_.LET B=C1
.s
sets B equal to the contents of the parameter C of the first enclosing process
.s2
And similarly
.s
_.LET Q3=C2
.s
sets parameter Q in the third outer process equal to parameter C in
the second outer process.
.s
See also section 9.4.
.HL2 Octal Expressions
.index Octal Expressions
The "LET" command may also be used to manipulate octal values. An
octal number is always preceded by a "%" sign.
.s
E.g.
.S
_.LET A=%11
.s
will assign the value 9 (decimal) to parameter A. Similarly,
.S
_.LET C=%13+%17
.S
would store 26 (decimal) in parameter C.
Also the format
.s
_.LET %A=12
.s
will store 14 (octal) in parameter A and
.s
_.LET %A=%A+1
.s
will then store 15 (octal) in parameter A.
.tp10
.nt
As MIC stores all variables as typeless strings it is up to the user
to ensure that he puts "%" signs where appropriate.
.en
.s
.tp 10
Parameters may also be regarded as storing a number in octal by preceeding the parameter name by a "%" sign.
.s
E.g.
.S
_.LET A="12"
.S
_.LET B=%A
.S;
will store 10 (decimal) in parameter B.
.S2
Octal and Integer values may occur together in the same expression.
.s
E.g.
.S
_.LET A=3+%11
.S
would give the value 12 (decimal) in parameter A.
.S
In order to make the manipulation of octal quantities more meaningful
two extra operators are available:-
.S
"_&" for AND
.S
"!" for OR
.S
which may be used with both octal and integer values
.S
.nf
E.g.
.S
_.LET A=%3_&%5 1
.S
_.LET A=3!5 7
.S
_.LET A=%11+7!%11 24 (DECIMAL)
.f.s
Note that "_&" and "!" have the same operator precedence as "*" and "/".
.pg
.HL1 Extensions to the IF command
.INDEX IF
.index IF Command
.index IF Extensions
Using the LET command complicated MIC command parameters may
be broken down. The conditional expression in the MIC IF
command may be used to make more generalised comparisons.
Using relational operators strings or integers may be compared.
.s
.nf
.TS 8,16,24,32,40,48,56,64,72
Relational Operator Meaning
.s
> greater than
>= greater than or equal
= equal
_# not equal
<= less than or equal
< less than
_.AND. AND (result non-zero implies TRUE)
_.OR. OR (result non-zero implies TRUE)
.F
.s
.index String-comparisons
String comparison occurs from left to right. Corresponding
characters are extracted from the constructed strings and
if they are not the same or either string is exhausted,
the result is false.
The relational operator is applied to the two characters
using their ASCII value.
String expressions may not be compared with arithmetic, and the ".AND." and ".OR." relational operators
may not be used with strings.
.s
A conditional expression containing a syntax error has the value false.
.s
If the error trapping feature has been enabled using the ERROR
command the ERROR and NOERROR conditional can be used to
alter command processing appropriately.
.s
If the conditional expression is true MIC will pass characters after the
first character "." on the right of the conditional to the monitor.
If the conditional is false, remaining commands on the IF line
are ignored.
.s
E.g.
.s.nf
_.IF (A>B) .GOTO LABEL
_.IF ($A="TRUE") .BACKTO TRUE
_.IF (ERROR) .GOTO FIX
_.IF (A.AND.%B) .GOTO FRED
.s.f
N.B. In the first example parameters A and B must contain
text which may be read as an integer. $A is used to reference
the contents of parameter A as a string.

By default lower case letters are ^¬\& considered to be the same
as upper case during string comparisons, though this may be changed by
use of the "MIC SET NO LC" command. See section 12.7.

Parameters in outer processes may be referred to in "IF" statements by
the method described in section 5.3
.S
N.B. Unlike the "IF (ERROR)" and "IF (NOERROR)" the "IF" extensions
actually run MIC and thus destroy the user's core image.
.HL2 Special Tests
Some special tests are built into MIC:-
.s
_.IF (COJOB)
.s
is true if this macro is running as a COJOB,
.s
_.IF (SUBJOB)
.s
is true if this macro is running under OPSER,
.s
_.IF (BATCH)
.s;
is true is this macro is running under BATCH,
.s
_.IF (TERMINAL)
.s;
is true if this macro is running on a terminal.

.HL1 Simple Interaction with MIC
.index Interactions
.s
A MIC command is obeyed as if the the user had typed the
same text on the teletype - "type ahead" is not allowed.
Some characters have a special meaning if typed by the
user as the MIC command is obeyed.
.s
As MIC commands may be nested,
control A is used to abort the current MIC process and return
to the level above.
.index Control A
.INDEX _^A
Control C will cancel all MIC processes
the user has in progress. An appropriate message is displayed on the
teletype.
.s
To allow limited user intervention control B will suspend MIC
typein and display [BREAK]. The MIC process may be continued by the user typing a
PROCEED command or a control P. The
message [PROCEED] will then be displayed.
.index Control P
.INDEX _^C
.INDEX _^P
.s
Note that while a process is suspended a user may
type MIC commands on the teletype as well as any
monitor commands. This implies that the MIC control functions
have their usual effect,
and, for example, using a control C to exit from "PIP" will cancel the suspended MIC process.
.HL2 OPERATOR/NOOPERATOR Commands
.index OPERATOR
.INDEX NOOPERATOR
.INDEX OPERATOR Character
Similar to the ERROR command the OPERATOR command takes as its argument one ASCII
printing character to be treated as introducing a line requiring user
attention. If the operator character is seen output in column 1, MIC
will suspend typein and display [BREAK].
.INDEX [BREAK]
The user may supply typein as required and type control
P (PROCEED) to continue processing the command file.
During a BREAK the operator character may be output again in column
one to PROCEED automatically, and [PROCEED] will be displayed.
.INDEX [PROCEED]
.s
E.g.
.s
.nf
_.OPERATOR N
_.RUN TEST
NOW TYPE IN YOUR NAME = [BREAK]CYRIL
NICE ONE CYRIL
_.[PROCEED]GOTO IT
.f
.s
The operator features are only available after an OPERATOR command.
The default character to the OPERATOR command is "?".
.INDEX ?
.tp20
.HL2 MIC RESPONSE Command
.INDEX MIC RESPONSE
.INDEX RESPONSE
Often it is required to inspect text displayed by a program particularly
when it denotes an error. The MIC RESPONSE command allows characters
displayed after an error character in column one to be placed in a named parameter.
The format for a MIC RESPONSE command is-
.s
_.MIC RESPONSE <parameter name>(<number of characters required>)
.s
E.g.
.s
MIC RESPONSE A(21)
.s
If the error feature has been enabled up to 79 characters
following the error character will be placed in the named parameter. The command
is used to reserve space for the response and the parameter is filled with spaces.
When an error occurs the text on the error line is copied character by character
until a null character is encountered in the reserved space or in the error text. Any remaining space is removed from the named parameter.
.HL2 MIC DISPLAY Command
.INDEX MIC DISPLAY Command
This command is used to output the contents of a user parameter or
parameters on the user's terminal.
.S
E.g.
.S
_.LET A="HELLO FRED"
.S
_.MIC DISPLAY A
.br
HELLO FRED
.br
_.
.s
This output overrides any silence condition which has been set up, and
is equivalent to
.s
!'A
.S
with the notable difference that it destroys the user's core image.
.tp 25
.nt
1.##This command is useful in immediate mode - see section 15 - and when
used in WHENEVER/ON commands - see section 11. Note that in this case
they do not destroy the user's core image.
.s
2.##Multiple parameters may be DISPLAYed by separating each by a comma
.s
E.g.
.nf.s
_.LET A="FIRST"
_.LET B="-AND-"
_.LET C="SECOND"
_.MIC DISPLAY A,B,C
FIRST-AND-SECOND
_.
.f.s
3.##String constants may also be displayed by enclosing them in (") quotes
.s
_.MIC DISPLAY "THIS IS A MESSAGE"
.br
THIS IS A MESSAGE
.S
4.##System parameters may be displayed in a similar fashion to user parameters
.s
_.MIC DISPLAY '<system-parameter> or
.br
_.MIC DISPLAY system-parameter
.s
See section 9.2 for further details of system parameters.
.s
5.##If an up-arrow "_^" occurs when a string parameter is being displayed
the next character in the string will be converted into a control
character in the usual way.
.en
.tp15
.HL2 MIC TYPE Command
.INDEX MIC TYPE
The MIC TYPE command has a similar format to the MIC DISPLAY command and
types the contents of a user parameter as though the user had typed them.
.s
E.g.
.nf.s
_.LET A="DIR
--"
.ps 62,75
_.MIC TYPE A
DIR
_.
_%DIRECTORY IS EMPTY
.f.s
The comments made for the MIC DISPLAY command also apply to the MIC
TYPE command.
.ps 60,75
.HL2 MIC WHAT Command
.INDEX MIC WHAT
The MIC WHAT command is used to output a brief status report on the
user's currently active macro.
.s
E.g.
.S
.nf
_.MIC WHAT
ACTIVE [100,100] 53 B2 A=FRED,B=6,C=JIM2
[MIC WHAT]
.S
where:-
.S
ACTIVE - is the current state of the macro
53 - is the user's line number
B2 - is the name of the user's macro
A= ETC. - are the contents of the user's parameters
[MIC WHAT] - is the last line typed by MIC on the user's
behalf.
.HL2 MIC SLEEP Command
.index MIC SLEEP
.index SLEEP Command
The MIC command is used to cause MIC to want a certain number of seconds before typing the next command.
.s
E.g.
.s
_.MIC SLEEP n
.S
where n is the number of seconds to wait.
.tp10
.HL2 MIC INPUT Command
.index MIC INPUT
This command is used to accept the input of a parameter value from
the user's terminal from within the processing of a MIC command file.
.s
The format of the command is:-
.s.nf
_.MIC INPUT p
.s
or
.s
_.MIC INPUT p,"<prompt-message>"
.s
.tp 20
where
.s.f
p is the parameter, normally A to Z, for which the value is to be
supplied. However parameter values may also be input to parameters in
outer nested processes by specifying A1, G3, etc. - (see section 6.1
Parameters in Outer Processes) and
.s
<prompt-message> is the message output to the user to invite him to
type in the line of input. If the prompt-message is omitted then the
input will be prompted for the display of "Enter parameter p". The
prompt message may be either a string variable or a string constant and
may include carriage returns and linefeeds. If it contains double-quotes
(") then they must be doubled ("").
.s
The execution of the MIC INPUT command allows the user to input
a single line of information from his terminal and have it included
in parameter p. The line should not be in double quotes, though it
may include double quotes and the input will end on any break character.
.s
This command overrides any silence condition in order to display the
prompt message and accept the input. The job will, if appropriate,
return to the silenced condition after the input has been accepted.
.s
The MIC INPUT command uses the BREAK and PROCEED facilities of MIC and when MIC has displayed
the prompt-message it enters the BREAK state until the input has
been read whereupon the process proceeds automatically. However the
normal [BREAK] and [PROCEED] messages are not displayed and any
action which the user has defined for [BREAK] or [PROCEED]
(using WHENEVER/ON) will be ignored.
.s
.tp20
E.g.
.s.nf
&.MIC INPUT A ;typed from MIC macro
^&Enter parameter A?\& 63 ;63 typed by user
&.
.s
or
.s
&.MIC INPUT C1, "What is your name?"
^&What is your name?\& IAN
&.
.s
or
.s
&.LET B=What is 2 multiplied by 2?"
&.MIC INPUT X,$B
^&What is 2 multiplied by 2?\& 3
&.
.tp10
.nt
1.##This command destroys the user's core image.
.s
2.##The prompt string may use string concatenation and subscripting.
.s
3.##When displaying the prompt string the sequence _^ch will cause
the character control-ch to be displayed, however the input will
store the two characters _^ and ch not control-ch.

! THIS JOB IS JOB NUMBER '<JOB>
.s
Would result in:-
.s
MY PPN IS [2250,7]
MY TTY IS TTY21
THIS JOB IS JOB NUMBER 10
.HL3 GETTABS

The three parameters of a GETTAB are:-
.s
Table
.s;
The table number in decimal of the required GETTAB table. The default
is table 0.
.s
Item
.s;
The index to the entry in the table. This index is in decimal, and the
default value is the user's job number. Note that as in the GETTAB UUO
-1 may be used to imply the user's job number.
.s
.INDEX GETTAB Radix

.s
This is a type-out mode taken from the following set which is used to
decode the entry in the GETTAB table.
.s2.nf.tp8

9 OC2 OCTAL (with leading zeroes suppressed)
10 DAT Date in DD-MON-YR (entry in 18-bit)
.S2
As an example of the use of GETTABS
.s
!'<GETTAB(25,-1,SIX)>'<GETTAB(26,-1,SIX)>
.s
would cause the user's "USERNAME" to be output.

.s.f
where A is a parameter.
.nt
In early versions of MIC the type-out mode was specified by the numeric
value given the the above table (e.g. 4 for decimal). This format will
still work: '<GETTAB(25,'A,ASC) and '<GETTAB(25,'A,2)> are equivalent.
.en
.HL3 Octal Arguments to GETTABS

.Index Octal Arguments to GETTABS
GETTAB arguments may be supplied in octal by preceding the argument by
a "%" sign,

_'<GETTAB(%11,-1,ASC)>
.F.S
This format is useful as the GETTAB tables are specified in octal in
the Monitor Calls Manual.
.PG
.HL2 Action Parameters
A special class of MIC parameter is the ACTION parameter. This type of
parameter performs a MIC action without destroying the user's core image.
.S
E.g.
.S
'<SILENCE>
.S;
will cause the macro to be silenced. This is similar in effect to the
.S;
_.SILENCE
.S
command except that the '<SILENCE> does not cause MIC to be run and does
not cause anything to appear in the user's terminal, not even the echo of the command.
.S.nf
The full list of action parameters is:=
.index ABORT
.index BREAK
.index CANCEL
.index ERROR
.index NOERROR
.index NOOPERATOR
.index OPERATOR
.index PROCEED
.index RETURN
.S
'<ABORT>
'<BREAK>
'<CANCEL>
'<ERROR(ch)>
'<NOERROR>
'<NOOPERATOR>
'<OPERATOR(ch)>
'<PROCEED>
'<RETURN>
'<REVIVE>
'<SILENCE>
'<SLEEP(n)>
.S
.index REVIVE
.index SILENCE
.index SLEEP
.F
and all of these have the same effect as the respective commands.
.S
The effect of an action parameter is always from the start of the line
in which it occurs.
.S;
E.g.
.S
_'<SILENCE> ABCDEF
.S
_'ABC '<SILENCE> DEF
.S
_'ABCDEF '<SILENCE>
.S;
are all equivalent.
.tp 15
.HL2 Miscellaneous Special Parameters
This is a group of parameters for specialised use.
.index Miscellaneous Special Parameters
.HL3 '<PSHIFT>
.index PSHIFT
.b
The PSHIFT or parameter shift command causes all parameters to be
shifted by one, that is
.s
######discard the contents of parameter A,
.br.nf
then
######A:=B, B:=C, C:=D ... X:=Y, Y:=Z
and
######Z:=null
.s.f
This command may be used in a loop for processing a string of
identical parameters.
.HL3 '<PROTATE>
.index PROTATE
.b
Like PSHIFT the PROTATE or parameter rotate command causes all
parameters to be shifted by one. The difference is that PROTATE
sets Z equal to A instead of discarding A. For example:
.s.nf
save the contents of parameter A,
then
A:=B, C:=D, ... X:=Y, Y:=Z
and
Z:= the saved contents of A
.HL3 String Constants
.index String constants
.b
Several commonly used strings of constants are now available as
MIC parameters.
.HL4 ALPHABET
.br
.index ALPHABET
The _$ALPHABET or '<ALPHABET> parameter returns a string of the
characters A through Z.
.HL4 NUMERIC
.index NUMERIC
.br
The _$NUMERIC or '<NUMERIC> parameter returns a string of the
4567890.
.HL4 ASCII
.index ASCII
.br
The _$ASCII or '<ASCII> returns the characters with values 1 through
127 in ASCII character set.
.s.nf;Note
LET A=$ASCII.[50]
returns the character whose ASCII value is 50.
.HL4 CR
.index CR
.br
The $CR or '<CR> returns a single carriage return character.
.HL4 CRLF
.index CRLF
.br
The $CRLF or '<CRLF> returns a string of the two characters
<carriage-return> and <line-feed>.
.HL2 Substitution of Parameters in Outer Processes
It is often required to substitute the contents of a parameter in an outer nested process in a similar way to the "'parameter-name" used for parameters
at the current level. As the syntax "'A1" cannot be used due to
possible confusion the syntax is '<parameter-name-level>.
.s
E.g. to substitute parameter Q in the third outer process we use
.s
######'<Q3>
.S2
.INDEX LET Command
.Index LET Extensions
.pg
.HL1 LET and IF Extensions
.HL2 Use of System Parameters
The LET command has been extended from that described earlier to allow the
user access to the system parameters described in section 9. By using the
LET statement with a system parameter on the right hand side a user may
use the byte subscripting features of MIC to abstract the portions of a
system parameter that he requires.
.s
_.LET B=$JOB
.s
This statement will store the user's job number in parameter B.
.s
Similarly,
.s
_.LET B=$PROJECT
.s;
will place the user's project number in parameter B.
.s
Concatenation of system parameters is allowed,
.s;
E.g.
.s
_.LET B="["+$PROJECT+","+$PROGRAMMER+"]"
.s
may be used to obtain the PPN of a MIC user.
.s
Byte subscription of system parameters is allowed,
.s
_.LET B=$PROJECT.[-1]
.s
would give the rightmost digit of a user's project number.
.S2
.HL2 Use of System Parameters in Arithmetic Assignments
System parameters may also be used on arithmetic assignments. However,
as all except "JOB" and "GETTAB" return only octal numbers it is not
normally a sensible operation, (except with "JOB" and "GETTAB"), unless
they are preceeded by a "%" to indicate that they are to be treated as
being octal.
.s
E.g.
.s.nf
_.LET A=JOB+2
or
_.LET A=GETTAB(1,2,DEC)+JOB-3
or
_.LET A=%TTY
or
_.LET A=%100_&%GETTAB(%53,-1,OCT)
.pg
.HL2 Use of System Parameters in IF Commands
In a similar fashion to 10.2, system parameters may be used in "IF"
commands, for example to ensure that a particular MIC macro is only run
on a specified terminal, the following check could be included in the macro:-
.s2.nf
_.IF ($TTY_#"21") .MIC ABORT
.s
or
.s
_.IF (%TTY_#21) .MIC ABORT
.f.s
The octal arithmetic facility may be combined with the GETTAB parameter to enable bit testing
of the system tables.
.s
E.g.
.s
_.IF (%GETTAB(A,'C,OCT).AND. %004001) .LET A="YES"
.PG
.HL1 Non Procedural Calls to MIC (WHENEVER/ON Command)
.INDEX Non Procedural Calls
Simple user interaction with MIC has been described in section 7,
but often the MIC action, on detecting an error condition or one of the special control functions, is not the required action.
A WHENEVER/ON command may therefore be used to
change the default action.
.s
.INDEX WHENEVER Command
.INDEX ON Command
The format of this command is:-
.s
_.WHENEVER <EVENT>:<ACTION>
.s;
or
.b
_.ON <EVENT>:<ACTION>
.S2;
(NOTE: ON and WHENEVER are synonymous)
.S2
The effect of this command is to specify that whenever the <EVENT>
occurs, the specified <ACTION> will be performed rather than the normal default action.
.s
E.g.
.s
_.WHENEVER BREAK:GOTO FRED
.s.f
This sets up the user's MIC process so that
whenever he types control B, or a MIC BREAK occurs the process
will not BREAK but rather will obey the GOTO FRED command.
.INDEX Events
.s 2
The valid events are:-
.s 2
.nf
CANCEL or Control C typed by the user
.s
ABORT or control A typed by the user
.s
BREAK or control B typed by the user
.s
PROCEED or control P typed by the user
.s
and
.s

1.##If ERROR trapping is enabled
.s
E.g.
.s
_.ON ERROR:ABORT

label; the ABORT is obeyed immediately.
.s;2.##If CANCEL trapping is enabled
.s;E.g
.s;_.ON CANCEL:_<action_>
.s;then the action is reset to the normal action after every occurrence
of the event. This only applies to ON CANCEL, and is to prevent users from accidentally creating macros which cannot be terminated. This feature may
be changed by MIC SET CCTRAP, see next section.

_.WHENEVER CANCEL:GOTO FRED,ABORT:GOTO BILL
.PG
.HL1 MIC SET Command
.INDEX MIC SET
This family of commands is used to change the action "MIC"
performs upon certain conditions.
.s
The format of the command is:-
.s
_.MIC SET <NO> <ACTION>
.s
E.g.
.S
_.MIC SET NO PARAMETERS
.s
This causes MIC to perform no parameter substitutions
upon detecting a "'" character in the input file.
.s
i.e.
.s
'A will "substitute" as 'A
.s
To restore parameter substitution use:-
.s
_.MIC SET PARAMETERS
.s
The MIC SET command currently available are:-
.HL2 COLUMN1
.INDEX COLUMN1.
.INDEX COLUMN ONE.
_.MIC SET NO COLUMN1
.S
MIC regards no characters in column one of the user's command file as
being special characters (see section 3).

.s
_.MIC SET COLUMN1
.HL2 Control Characters
.INDEX CONTROL

as satisfying a search for a label (cf. section 4.1).
.s
The default is:-
.s
_.MIC SET FINMATCH
.HL2 MSGLVL
.INDEX MSGLVL
.S
The "MIC SET NOT MSGLVL n" may be used to suppress the output of the
messages "[ABORT]", "[BREAK]", "[CANCEL]", and "[PROCEED]". The
argument "n" is a octal number which is used to specify which messages
the user wishes to suppress.
.s.nf
1 supresses [ABORT].
2 supresses [BREAK].
4 supresses [CANCEL].
10 supresses [PROCEED].
.tp12
.HL2 LC
.INDEX LC
_.MIC SET NO LC
.s.f
This causes lower case and upper case characters to be treated as
equivalent in string comparisons.
.S
The default is:-
.S
_.MIC SET LC
.HL2 TRACE
.index TRACE
This is a feature which a user may use when debugging a completed MIC
macro. If the command
.s
_.MIC SET TRACE
.s
is executed, then MIC displays all labels that are processed during
search commands (GOTO/BACKTO or implied GOTOs due to errors).
.s
The first six characters of every label are displayed in square brackets, and a carriage return is not displayed until the last label is processed.
Also MIC will display [TRUE] or [FALSE] on the execution of every "IF" conditional command.
.HL2 SILENCE
.index SILENCE
This is another feature which is useful in debugging MIC macros. If
the command
.s
_.MIC SET NO SILENCE
.s
is executed, then MIC will ignore all attempts to silence the current,
and any nested, MIC macros. The default is:-
.s
_.MIC SET SILENCE
.HL2 CCTRAP
.INDEX CCTRAP
This command is used to enable multiple occurrences of ON CANCEL:_<event_>. If the command

Several SET functions may be performed in the same command by separating each of the functions by a comma, thus:-
.s
_.MIC SET NO PARAMETERS,CONTROLS,NO FINMATCH
.PG
.HL1 CCL Entry to MIC
.index CCL Entry to MIC
The CCL entry to MIC provides a user program interface to MIC. If MIC
from SYS is run with a runoffset of 1 (by a RUN UUO), MIC will attempt
to read command input from a TMPCOR file called "MIC", or if that is
not available, from a disk file "nnnMIC.TMP" (where nnn is the user's
job number), rather than from the terminal.
.INDEX TMPCOR
.b
This file may contain a single line of input to MIC
.s
E.g.
.s
_.TYPE TMP:MIC
.br
.in do
/DOIT A,36,C
.else do
DO DOIT A,36,C
.ei do
.br
_.
.s
would cause the MIC macro "DOIT" to be executed if MIC is run with a runoffset of 1.
.s2
The file may contain any MIC command, e.g. LET, IF, GOTO, etc. though in
this case the user must be already running under MIC, otherwise he will
get an appropriate error message. This provides a means of manipulating
MIC parameters via a user program, the user program simply writes a TMPCOR file
and runs MIC as above, with and appropriate "LET" command in the TMPCOR file.
.nt
1.##The CCL input file is deleted by MIC.
.S
2.##Use of TMPCOR is described in the Monitor Calls Manual.
.S
3.##Use of the RUN UUO is described in the Monitor Calls Manual.
.S
4.##Those CUSP's which are loaded with SCAN, (e.g. LOGIN, QUEUE,
DIRECT, etc.) have a "/TMPFIL" switch, which has the form
.S
/TMPFIL:<NAME>:"<TEXT>"
.S
where:-
.S
<name> is the three character name of a TMPCOR file
to be created
.INDEX TMPFIL
.S
<text> is the contents of the TMPCOR file.
.s
5.##The TMPCOR file does ^&NOT\& contain the monitor dot or data asterisk.
.en
This switch may be used to create a MIC TMPCOR file and the
"/RUN:MIC/RUNOFFSET:1" switches used to cause the file to be obeyed.
.S
.tp 10
E.g.
.s
Say a user wished to run a macro called "SETUP" everytime he logged in;
he may type:-
.S
.in do
_.LOGIN 110,1/RUN:MIC/RUNOFFSET:1/TMPFIL:MIC:"/SETUP"
.else do
_.LOGIN 110,1/RUN:MIC/RUNOFFSET:1/TMPFIL:MIC:"DO SETUP"
.ei do
.S
.f
As this command is rather long the user would probably include all or
part of it in his "SWITCH.INI" files. (Consult the Operating Systems
Commands Manual for a description of "SWITCH.INI" and the above
switches.)
.pg
.HL1 Multiple Statements on a Line
.Index Multiple Statements on a Line
.INDEX _\ (backslash)
More than one MIC command can be written on a single line by
terminating each command by a "_\" character.
.S;
E.g.
.S
_.LET A=3,B=4 _\ .GOTO JIM
.S
This is especially useful in the case of "IF" statements.
.s
E.g.
.S
_.IF ($A="DONE") .LET Z="FINISH" _\ .GOTO DUNIT
.nt
1.##This only applies to MIC commands. It does not include normal monitor commands, except when the monitor command is the last command on the line.
.s
E.g.
.s
_.LET A=3,B=4 _\ .ERROR ? _\ .DIR ZXCV.ALG
.s
2.##All parameter substitution is performed for the whole line before
the first statement is obeyed.
.s
This means that (assuming parameter A contains "DIR FRED") an input
construction of the form:-
.s.nf
_.LET A=$A.[1,3]+" JIM" _\.'A
.s
would result in
.s
_.LET A=$A.[1,3]+" JIM" _\.DIR FRED
.s
being obeyed.
.S.f
3.##If a error occurs in a statement all subsequent statements on that
line will be ignored.
.S
4.##The "_\" may be omitted after several MIC commands, for example the
"REVIVE" command, for compatability with older macro files.
.s1
5.##In the case of syntax error in a MIC command preceeding a "_\", the
rest of the line will usually be ignored.
.en
.PG
.HL1 Immediate Mode Execution of MIC commands
When a MIC macro is in [BREAK] mode the user may type (to
monitor) any MIC command in addition to any monitor command. This allows
the user to suspend his macro and examine and manipulate his parameters - useful
when debugging complex macros - or perform some action on behalf of the macro.
.S
The GOTO and BACKTO commands when used in this manner
do not take effect immediately, but are effective as soon as the MACRO is proceeded.
.s 2
N.B.
.S;
A special case of the MIC DISPLAY command may be used at any
time, even when the user is not running under MIC. This is the
.S
MIC DISPLAY <system-parameter>
.S
This can be very useful for obtaining information from GETTAB tables
(see sections 7.3 and 9.2) though the user should be aware that the use of
this command does destroy his core image.

.ax Syntax of integer and string expressions
.HL1 Integer Expressions
The operators +, * and - have the conventional meaning. The character _/ is used for
divide, _^ for exponentiation, _& for logical AND, and ! for
logical OR. The evaluation of an expression is from left to right with
precedence as follows:-
.nf.s
_^ first
*/_!_& second
+- third
.s.f
Matching round brackets may be used to arrange the desired order of execution of operations. The monadic operator
- is allowed but the monadic + is not allowed, since unsigned
integers are assumed positive.
.s
Examples:-
.s
.nf
-2*(3+2-1)_5*(6/2+2) is legal
.s
+2 is not legal
.s
2+(-3*(4*(6+1))) is legal

To allow references to be made to parameters in an outer process a
qualifier is allowed to the parameter name, e.g.
.s
If a MIC command is nested three deep A3 would be the
parameter A in the outer process. This extension also applies to
string parameters ($A3).
.S
On the left hand side of LET assignment statements the qualifier may be
used to return parameters to an outer level MACRO command, e.g.
.S
_.LET A1="TEXT"
