^^With the SIMDIR program you can easily find out:
_> Which separately compiled modules are used by one  or  several  main
programs.
_> Which program modules use a certain separately  compiled  procedure
or class.
.SKIP
To start the program type:
_.R SIMDIR
SIMDIR responds with a "*" , signalling that it is ready for a command.
.SKIP
In the simplest case, you can now write:
.SKIP
   SEARCH /ALL REQUIRED BY main
.SKIP
This will list all modules on your PPN which are used by the  module  main.
This  module main is usually a SIMULA main program, but can be a separately
compiled module.
.SKIP
   SEARCH /ALL USING proc
.SKIP
This will list all modules on your PPN which use  the  separately  compiled
module proc.
.SKIP
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 write:
.SKIP
   DIRECTORY [*,*]
   SEARCH /ALL USING proc
.SKIP
This will give a listing of all SIMULA programs  on  all  PPN:s  which  are
using your separately compiled procedure proc.
.SKIP
As input SIMDIR has the ATR-files  from  separately  compiled  classes  and
procedures  and  the  REL-files from main programs.  This means that SIMDIR
only works when such ATR and REL files are present for the programs  to  be
listed.
.SKIP
The syntax of the SIMDIR commands is:
.SKIP
_<SEARCH-command_>::= SEARCH _<pattern_> [_<relation_>[_<pattern_>]]
   _<relation_>::= USING _! REQUIRED BY
   _<pattern_>::= [_<device_>][_<filename_>][_<ppn_>][_<switches_>]
   _<ppn_>::= _<left bracket_>_<ppn1_>_<right bracket_>
   _<ppn1_>::= SELF _! OTHERS _! _<pnr_>,_<pnr_>
   _<pnr_>::= _! * _! _<octal number_>
   _<switches_>::= _<switch_> _! _<switches_>_<switch_>
   _<switch_>::= /_<switchname_>
   _<switchname_>::= ALL _! MAIN _! CLASSES _! PROCEDURES _!
           FPROCEDURES _! SPROCEDURES _! MPROCEDURES _!
           FAST _! TTY
   _<device_>::= _<name_>:
   _<filename_>::= _<name_>
.SKIP
   SEARCH _<pattern_> means that all modules matching  the  pattern  will  be
   searched for and listed.
.SKIP
   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.
.SKIP
   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.
.SKIP
   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, however.
.SKIP
   There are two special PPN:s that you may use in a pattern: [SELF] is the
   PPN  that  the  job  is  logged in under.  [OTHERS] stands for all those
   PPN's that have been given  in  DIRECTORY  commands  and  that  are  not
   [SELF].
.SKIP
   The meanings of the switches are:
           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.
.SKIP
.SKIP
_<DIRECTORY-command_>::= DIRECTORY _<directories_>
   _<directories_>::= _<directory_> _! _<directory_>,_<directories_>
   _<directory_>::= [_<switch_>] _<ppn_> [_<switch_>]
   _<switch_>   ::= /MAIN _! /-MAIN
.SKIP
   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.
.SKIP
.SKIP
_<LIST-command_>::= LIST _<file specification_>
.SKIP
   Program  output  is  written  on  the  specified   file.    Default   is
   DSK:SIMDIR.LST
.SKIP
.SKIP
_<CLOSE-command_>::= CLOSE
.SKIP
   The current list file is closed.
.SKIP
.SKIP
_<EXIT-command_>::= EXIT
.SKIP
   Close current list file (if any) and return to monitor.
.SKIP
.SKIP
_<HELP-command_>::= HELP [ /TTY ]
.SKIP
   Output help-text.
.SKIP
.SKIP
All  "reserved  words"  (upper  case  letters  above)  can   be   shortened
arbitrarily.  Any conflicts are resolved as follows :
   /M means /MAIN
   /F means /FAST
.SKIP
.SKIP
When SIMDIR is started a *D[S]/M command is automatically performed.
.SKIP

EXAMPLES:
.SKIP
List all SIMULA modules on your own PPN

.SKIP
List those of your own modules  which  are  used  by  others  in  the  same
project.
