With the SIMDIR program you can easily find out:
> Which separately compiled modules are required by one or several main
> Which program modules require a certain separately compiled procedure
To start the program type:
SIMDIR responds with a "*" , signalling that it is ready for a command.
In the simplest case, you can now write:
SEARCH /ALL REQUIRED BY main
This will list all modules on your PPN which are used by the module
main. main is usually a SIMULA main program, but can be a separately
SEARCH /ALL USING proc
This will list all modules on your PPN which use the separately compiled
You can precede the SEARCH command with a DIRECTORY command to tell the
system to include other PPN:s in the search. For example, you can
SEARCH /ALL USING proc
This will give a listing of all SIMULA programs on all PPN:s which
require your separately compiled procedure proc.
As input SIMDIR requires ATR-files from separately compiled classes and
procedures and REL-files from main programs. This means that SIMDIR
only works when such ATR and REL files are present for the programs to
The syntax of SIMDIR commands follows:
<SEARCH-command>::= SEARCH <pattern> [<relation>[<pattern>]]
<relation>::= USING ! REQUIRED BY
<ppn>::= <left bracket><ppn1><right bracket>
<ppn1>::= SELF ! OTHERS ! <pnr>,<pnr>
<pnr>::= ! * ! <octal number>
<switches>::= <switch> ! <switches><switch>
<switchname>::= ALL ! MAIN ! CLASSES ! PROCEDURES !
FPROCEDURES ! SPROCEDURES ! MPROCEDURES !
FAST ! TTY
SEARCH <pattern> means that all modules matching the pattern
will be searched for and listed.
SEARCH <pattern> <relation> means that all modules matching the
pattern will be searched for and listed together with the
modules which have the given relation to the modules.
SEARCH <pattern> <relation> <pattern> means that all modules
matching the first pattern and having the given relation to any
module matching the second pattern are listed.
A module matches a pattern when it matches all components of
that pattern. If any component is missing in a pattern, then
all modules match that component. The pattern may not be empty,
There are two special PPN:s that you may use in a pattern:
[SELF] is the LOGIN PPN. [OTHERS] stands for all PPN's except
[SELF] which have been given in DIRECTORY commands.
Explanation of switches:
ALL All modules match
MAIN Main programs match
CLASSES Classes match
PROCEDURES Procedures match
FPROCEDURES FORTRAN procedures match
MPROCEDURES MACRO-10 procedures match
SPROCEDURES SIMULA procedures match
FAST Do not output PPN
TTY Change output device
temporarily to TTY.
<DIRECTORY-command>::= DIRECTORY <directories>
<directories>::= <directory> ! <directory>,<directories>
<directory>::= [<switch>] <ppn> [<switch>]
<switch> ::= /MAIN ! /-MAIN
Include the given directories when searching.
/MAIN means that all modules are fetched from this directory,
/-MAIN that only external classes and procedures are fetched.
Default is /-MAIN.
<LIST-command>::= LIST <file specification>
Program output is written on the specified file. Default is
The current list file is closed.
Close current list file (if any) and return to monitor.
<HELP-command>::= HELP [ /TTY ]
All "reserved words" (upper case letters above) can be abbreviated
arbitrarily. Any conflicts are resolved as follows :
/M means /MAIN
/F means /FAST
When SIMDIR is started a *D[S]/M command is automatically
List all SIMULA modules on your own PPN
List those of your own modules which are used by others in the same
*SEARCH [SELF] REQ BY [OTHERS]
