.hl 1 Summary
.if vb
APL is the basic
.else vb
APLSF is the
.endif vb
implementation on the
.if VTEN
DECsystem-10
.else VTEN
DECSYSTEM-20
.endif VTEN
of the APL language with shared system functions and system variables.
It runs on a
.if VTEN
KI-10 or KL-10 processor under release 6.03A or later of the TOPS-10
monitor, and requires VMSER on the KI-10.  It requires no
other software modules during execution,
.else VTEN
KL-20 processor under release 3A or later of the TOPS-20
monitor.  It requires the compatibility package, PA1050,
during execution,
.endif VTEN
and is documented in the APLSF Programmer's Reference Manual
.if VTEN
(DEC-10-LPLSA-A-D).
.else VtEN
(DEC-20-LASFA-A-D).
.endif VTEN
Version 2 is documented in the TOPS-10/20 APLSF Language Manual
(AA-H200A-TK).
.b1
Version 2 runs under release
.if VTEN
6.03A or later of the TOPS-10 monitor.
.else VTEN
3A or later of the TOPS-20 monitor.
.endif VTEN
It has been tested in-house under
.if VTEN
6.03A and 7.00.
.else VTEN
3A and 4.
.endif VTEN
.b1
The reason for this release is to correct outstanding bugs in
.if vb
APL
.else vb
APLSF
.endif vb
Version 1C and to incorporate several functional enhancements
as described below.
.b1
.if vb

.pg
.hl 1 External Changes
.ls
.le;The current setting of )MAXCOR is now saved across a
)CALL, so it is possible to return from a )CALL even if
)MAXCOR had been expanded in the workspace before the )CALL.
.le;There are now TTY mnemonics for diamond (.DM), left
bracket (.LB), left tack (.LK), right bracket (.RB), and right
tack (.RK).
.le;Nonprinting elements of the atomic vector (.BXAV) are
now displayed as squish quad (.SQ).  Note that this is not a valid
character and cannot be typed to APL.
.le;When doing APL output to an ASCII sequential file while
in TTY mode, the default terminal type is now LA36 instead of
.if VTEN
2741.
.else VTEN
2741 (which is not supported by TOPS-20).
.endif VTEN
.le;Error numbers are now catenated to the front of error
messages.  Also, the error line printed when an error occurs
occasionally has fewer added spaces and the caret position
is sometimes one position to the right of where it used
to be.
.ifnot vten
.le;LIB: now refers to whatever the user has logical name
LIB: defined to be, instead of the APL system library.
LIBn: still refers to the system library.
.endif vten
.ifnot vb
.le;It is now possible to open a PTY as an ASCII
sequential file.  As noted in the next item, lower case
input will be converted to upper case just as with any
ASCII sequential file.  The new system variable .BXTIMEOUT
will be set if the input was not terminated with a line feed.
.le;When doing TTY mode input from ASCII sequential files,
lower case characters are converted to uppercase (instead of
random operators).
.endif vb
.le;The omega function (.OM) has been removed from the version 2 manual.
Omega still works in version 2 but will not be supported after version 2.
The .OM symbol has other proposed uses in the APL language and the optimizing
effect of .OM will be implememted for reduce-iota-rho.
.le;The definitions of I-beams (.IB) have been moved to an appendix of the
version 2 manual.  They are still supported in version 2 and most will still
be supported in later versions for compatibility with other vendors.  However,
we strongly recommend that system variables and functions be used instead of
I-beams.
.le;Quote-quad (.QQ) or quad-del (.QD) input following .QQ or .QD output
precedes the input string with a string of blanks equal in length to the
preceding output.  If such preceding output was longer than 390 characters
(the maximum input length), a LINE TOO LONG error occurs and correct input
is awaited.
.le;For niladic function F which returns no value, the expressions "1;F",
"1+F" and "F+1" give value errors since a value is needed by the primitive
function but F did not return one.  The expression "F;1" returns 1 to be
consistent with the expression "F", which executes F but prints nothing.
Note that the ";" function is a monadic output catenator, operating on the
expression to its right.  ";" is not intended to be a statement separator.
.ifnot VTEN
.le;On the -20,
.if VB
GENBAS
.else VB
GENSF
.endif VB
can now set the device for the library area and the )HI file as well as the
directory. The default is now PS: instead of DSK: so
.if VB
APL
.else VB
APLSF
.endif VB
will be able to find these areas even if you are not connected to PS:.  You
must be connected to the device specified for these areas when running
.if VB
GENBAS
.else VB
GENSF
.endif VB
in order for the generation procedure to be successful.
.ifnot VB
Notice that this device is also used for the billing file.
.endif VB
.endif VTEN
.els
.hl 2 Functional Changes
.list
.if vten
.le;The HIGH segment of
.if VB
APL
.else VB
APLSF
.endif VB
has grown by about 11 pages.  Users should monitor their memory use with
version 2 and if they notice substantial performance loss due to excessive
paging activity, they should ask their system administrator to raise the
global physical page limit on the system.
.else VTEN
.le;_.BXMTP has been modified to simulate some of the TAPOPs
not in PA1050.  It still has problems if the file has not
been opened.  Specifically, density and mode cannot be set from inside APL
before the file is opened.  Use the SET TAPE Exec command to set these
tape parameters.
.endif vten
.els
.hl 2 Functional Additions
.hl3 Error trapping
The following system variables and functions have been added
to allow program handling of error conditions and other events.
.list
.le;_.BXBREAK#-#This is a monadic function which causes
execution to terminate, suspending the current function and
entering immediate mode.  It prints its argument before
breaking to the terminal.
.le;_.BXERROR#-#This is a variable which is set by APL to
the error message for the last error.  (It contains the text
which is normally printed on the terminal.)
.ifnot VB
.le;_.BXSIGNAL#-#This is a dyadic function which signals an
error from the current function.  It causes the current
function to terminate before generating the error.  Its
right argument is either a valid APL error or a user defined
error in the range 500-999.  Its optional left argument is
the message to be associated with the error.
.le;_.BXTRAP#-#This variable is similar to .BXLX.   It can
be set to an expression which will be executed when an error
occurs.  
.endif VB
.els
.hl3 Limiting input wait
The following two variables allow a program to limit the
amount of time a user is given to respond to quote-quad or
quad-del input.
.list
.le;_.BXTIMELIMIT#-#The number of milliseconds to wait for
user input.  If 0, then no limit.  If -1, no waiting
is done (only characters which were typed ahead are read).
.le;_.BXTIMEOUT#-#Flag indicating whether or not user timed
out on last input.  (This flag is also used with PTYs to
indicate whether or not last input was terminated with a LF).
.els
.hl 3 New Character Arrays
The following system variables are useful subsets of .BXAV.
.list
.le;_.BXALPHA#-#The 27 letters, .LD-Z.
.le;_.BXALPHAU#-#The 27 underscored letters, [email protected].
.le;_.BXASCII#-#The 128 ASCII codes.  These codes are sent
to files as is, regardless of the terminal type.  They are
useful when doing graphics.
.le;_.BXCTRL#-#The 32 control characters, octal 0-37.
.le;_.BXNUM#-#The 10 digits, 0-9.
.els
.ifnot vb
.hl 3 New File Functions
.list
.le;_.BXRENAME#-#This is a dyadic system function which
allows a user to rename a file from within APL.  Its right
argument is the channel associated with the file to be
renamed.  Its left argument is the new filespec.
.le;_.BXAPPEND#-#This is a dyadic system function which
allows a user to append data to /BU or /DA files.  Its left
argument is the data item to be appended to the file.  Its
right argument has the same format as the right argument to
an output quad (.OQ) and specifies how the data is to be
formatted in the file.
.le;Two new file types, /AS* and /BS*, have been added to
allow users to append to ASCII and binary sequential files.
These file types are analogous to /IS*.

.hl 1 Known Bugs And Deficiencies
.hl 2 Deficiencies And Restrictions
The known deficiencies and restrictions in
.if vb
APL
.else vb
APLSF
.endif vb
are:
.list
.le;The caret symbol indicating where an error in an APL
statement was first detected is sometimes displayed in the wrong
position.  With the introduction of error trapping and
_.BXERROR, it is desirable to fix this.  We will attempt to
do so in the future.  With this in mind, we recommend
that users do not write programs which depend on the current
positioning of the caret.
.le;It is not possible to display the trace or stop vector of a
function.  This is a restriction which will not be removed in the
foreseeable future.
.le;It is impossible to enter an invalid TTY mnemonic in a character
string when using a TTY terminal, just as it is impossible to enter
an illegal overstrike from an APL terminal.  This is a permanent
restriction.
.ifnot VB
.le;Monadic domino uses an inordinate amount of core.  This is a
deficiency due to the algorithm used, which does monadic domino by
simulating a dyadic domino with a left argument of the identity matrix.
Thus, it must construct a double precision identity matrix.
.endif vb
.end list
.hl 2 Outstanding Bugs
The known outstanding bugs in
.if vb
APL
.else vb
APLSF
.endif vb
are:
.b1
.list
.le;Erasing a pendent or a suspended function can cause a SYSTEM ERROR,
depending on the state of the function when erased.
.le;The compression of a zero-by-n matrix returns a length error when
the left argument is an n-element vector, but works if it is a scalar.
.le;A niladic branch inside a multistatement line will fail with
a SYNTAX ERROR.
.ifnot VTEN
.le;Linefeeds typed during linefeed editing may appear as carriage
return linefeed pairs.  This is a temporary restriction which will
be corrected in version 4 of the compatibility package.  A
patch to PA1050 which solves this problem is included in the
beware file on this tape
.if vb
(APL.BWR).
.else vb
(APLSF.BWR).
.endif vb
.le;The )LIB command updates the access dates of the listed files.
In particular, )LIB/A updates the access dates to the current date
before printing them.  This is a problem with the compatibility
package.

6.0##SUGGESTIONS
.B1
6.1##Continuing a detached APL job
.B1
In the event of a line drop or system crash, a user's job may
become detached.  After reestablishing a connection with the
system, the user should check to see if his/her job is still there.
If so, the user should reattach to the job using the
ATTACH command.
Then, to restore the job to its previous state, the
user should type CONTINUE.  If the user instead types
.if vten
R
.endif vten
.IF VB
APL,
.ELSE VB
APLSF,
.ENDIF VB
a new version of APL will be loaded and
the job's previous core image will be destroyed, along with the user's
workspace.

1.0##SUMMARY
.b1
.if vb
APL is the basic
.else vb
APLSF is the
.endif vb
implementation on the DECsystem-10 of the APL language with
shared system functions and system variables. It runs on a KI-10 or
KL-10 processor under release 6.03 or later of the TOPS-10
monitor, and requires VMSER on the KI-10.  It requires no
other software modules during execution,
and is documented in the APLSF Programmer's
Reference Manual (DEC-10-LPLSA-A-D).
.b1
The reason for this release is to correct outstanding bugs in
.if vb
APL
.else vb
APLSF
.endif vb
Version 1B.
.b1
.if vb
APL
.else vb
APLSF
.endif vb
Version 1C runs under release 6.03 or later of the TOPS-10
monitor.  It has been tested in-house under 6.03A and 7.01.
.b1
.if vb
APL
.else vb
APLSF
.endif vb
Version 1C fully supersedes Version 1B and includes edits
_#302 to _#315.

2.1##Functional Changes
.b1
.list
.if vb
.le;GENBAS can now be run from any directory instead of only [1,2].
.else vb
.le;GENSF can now be run from any directory instead of only [1,2].
.endif vb
.le;Dyadic#!#now gives results over a wider range of arguments (e.g.
12!40).  It also computes results when the second argument is less
than zero, instead of returning 0 (it still returns zero when the second
argument is less than the first).  Also, monadic#!#not only gives results
for negative (non-integral) arguments, but the results are now correct.
.le;When character strings containing embedded CRLFs are printed, trailing
blanks before the carriage returns are removed.
.le;Terminal characteristics are now restored appropriately (the same
way they are set on entry) when REENTERing or CONTinuing from CTRL/C.

3.0##KNOWN BUGS AND DEFICIENCIES
.b1
3.1##Deficiencies and Restrictions
.b1
The known deficiencies and restrictions
in
.if vb
APL
.else vb
APLSF
.endif vb
are:
.list
.le;The caret symbol indicating where an error in an
.if vb
APL
.else vb
APLSF
.endif vb
statement
was first detected is sometimes displayed too far to the left.
This is a design problem with the interpreter, and there are no plans
to fix it in the immediate future.
.le;It is not possible to display the trace or stop vector of a
function.  This is a restriction which will not be removed in the
foreseeable future.
.le;It is impossible to enter an invalid TTY mnemonic in a character
string when using a TTY terminal, just as it is impossible to enter
an illegal overstrike from an APL terminal.  This is a permanent
restriction.
.if vb
.else vb
.le;Monadic domino uses an inordinate amount of core.  This is a
deficiency due to the algorithm used, which does monadic domino by
simulating a dyadic domino with a left argument of the identity matrix.
Thus, it must construct a double precision identity matrix.  We will
attempt to correct this deficiency soon.
.endif vb
.end list
.b1
3.2##Outstanding Bugs
.b1
The known outstanding bugs in
.if vb
APL
.else vb
APLSF
.endif vb
are:
.b1
.list
.le;Erasing a pendent or a suspended function can cause a SYSTEM ERROR,
depending on the state of the function when erased.
.le;The compression of a zero-by-n matrix returns a length error when
the left argument is an n-element vector, but works if it is a scalar.
.le;A niladic branch inside a multistatement line will fail with
a SYNTAX ERROR.
.le;If F is a niladic function which does not return an explicit
result, the construct _'_;F_;_' will give a VALUE ERROR.
.le;The random link variable .BXRL cannot be set equal to or greater
than 2_^27.  This will be fixed in version 2.
