   --- SIMULA Editor and Indentation program Version 2(6) ---

The SIMED program edits SIMULA source program files into  a  readable

SIMED can be used to indent a SIMULA program (for better readability)
according to the BEGIN-END structure.  This is especially useful when
the program contains BEGIN-END nesting  errors,  which  usually  will
produce unhelpful compiler messages.

SIMED  may  also be used to convert reserved words, standard and user
identifiers to -
1) UPPER CASE 2) lower case 3) Edit Case (1st char.  upper case).

Lines  which  become  too  long  when indented will be split up at an
appropriate position.

If one of the following conditions holds, comments are not indented -
a) The start of the line is part of a comment or
b) The end of the line is part of an (unfinished) comment.

Command format for SIMED (example):


Default switches:
/I:4		Indent  step  4. A non-positive argument implies that
                leading  tabs  and  blanks  will  be  preserved   and
                indented according to Abs(arg).

/E:13200	Edit  Reserved words, standard ids, own ids, Comments
/E:UEL00	and Options, Text and Character constants resp. 1 (U)
                =  Upper CASE, 2 (L) = Lower Case, 3 (E) = Edit case,
                0 = no  change.                    Thus  /E:000  will
                suppress all editing.

/R:80		Outfile record length 80.

/TABS           Use tabs in indentation (default)

/C		Check for non-unique  identifiers  with  length  >=12
                (producing warnings).

Other switches:
/SIMSET		Recognize SIMSET identifiers (default for SIMSET  and
                SIMULATION blocks)
/-SIMSET        Do not recognize SIMSET ids
/SIMULATION	Recognize   SIMULATION   identifiers   (default   for
                SIMULATION blocks)
/-SIMULATION    Do not recognize SIMULATION ids
/-TABS          Do not use tabs
/NUMBERED:xx	Produce line numbers, incr. xx (def. 100) (default if
                input file has numbers).
/-NUMBERED	Suppress       line      numbers      on      output.
		(default if input file has no line numbers).
/-C             Do not check long id:s (5-20% cheaper).
/Z:n		Suppress indentation for n block levels. May be <  0,
                >=      -10,     assuming     surrounding     levels.
                Default /Z:0.
/G		Perform  last  COMPIL  command after processing, i.e.
                last COMPILE,  LOAD  or  EXECUTE  command.
!xxx		Run program xxx after processing. Thus  ABC!SOS  will
                return  to  SOS editing last file edited. The command
                NUL:!SOS is also legal.

Your own default switches can also be given in a file  SWITCH.INI  on
your area.   You need only have one or more lines of the form:

SIMED /switch/switch...

Example:  If you want files to be edited with reserved words in lower
case,  your  own  identifiers  in upper case, and standard identifiers
with  upper  case  initial  letter,  standard  indentation=2,   record
length=100, put the following line in SWITCH.INI:

SIMED /E:LEU/I:2/R:100

Trailing zeros in the E switch may be omitted -  the  system  default
will  be used in those positions.  You can always override the default
values in the command to SIMED.

Default extension is SIM.  Default outfile name is infile name. (NUL:
and TTY:  are accepted.)

If you want only default values, the command string to edit the  file
X.SIM with the same output file name is simply X.

The shortest possible command to apply SIMED to a file X.SIM is -

.R SIMED-X      (@SIMED -X in TOPS-20)

SIMED will take what follows after a minus sign as the first  command
and  exit  after  editing.   CONTINUE  will put SIMED in command mode,
expecting further commands.  START or START-<command-string> may  also
be used.

Just typing -

will  start  SIMED  editing the last TECO/SOS edited file (by reading
TMP:EDS) using default switches (possibly redefined in SWITCH.INI).

Exit from SIMED by entering ^Z or ^C.


Split up lines will not be indented properly if they contain BEGIN or

Also,  numerical  constants  containing  blanks  may  occasionally be
improperly split.  The programmer is recommended to start source  code
lines with BEGIN and END resp.

Additional feature:

If  a  text  constant  includes  <CR><LF> SIMED will ask the user for
permission to continue, in order to prevent a possible messing  up  of
the  file.   Otherwise  if one of the quotes is missing all subsequent
(correct) text  constants  might  be  destroyed  by  Upper/lower  case
editing.   "Proper" text constants containing <CR><LF> will be changed
to new concatenated text contants now allowed in SIMULA.
