contain the documentation of the current version of  SIMULA 
that runs at SCORE.


This help file (HLP:SIMULA.HLP) contains general information
on  the  SIMULA system.  The current version is 4A(320), Oct
1978.  Information about changes  and  additions  in  SIMULA
releases  2,  3,  3A  and  4 can be found in DOC:SIMULA.DOC.
More specific information about the  SIMULA  system  can  be
obtained   by  issuing  the  monitor  commands  HELP  SIMCOM
(compiler information), HELP SIMDDT (debugging system), HELP
SIMRTS  (object  time  system), HELP SIMDIR (utility program
for separate compilation).  SIMULA Language Handbooks I,  II
and  III  are  available.   They can be ordered from FOA He1
Report Center,  S-10450  Stockholm,  SWEDEN.   SIMULA  is  a
general  purpose  language  which  contains  Algol  60  as a
subset.  In addition to the  facilities  offered  by  Algol,
SIMULA   is  especially  suited  for  list-processing,  text
handling  and  simulation,  through   the   class   concept,
reference  and  text variables and the system classes SIMSET
and  SIMULATION.   Input/output  is  efficient  and  closely
linked  to  the text handling facilities.  The class concept
is unique to SIMULA.  Through a class declaration,  one  can
define  a  data  structure and operations on the data as one
entity.  With suitable class  declarations,  SIMULA  can  be
turned  into  a  special  purpose  language  for  almost any
application field.  SIMULA also contains a powerful facility
for  separate  compilation  of  classes and procedures.  For
applications  where  useful  subroutines  are  available  in
FORTRAN  or  in assembly code (MACRO-10), it is easy to call
external procedures in those languages.   DEC-10  SIMULA  is
closely  compatible  with IBM 360/370 and UNIVAC 1100-series
SIMULA.  SIMULA programs written for these  systems  can  be
run almost unchanged.  For SIMULA programs written for other
systems, conversion programs are available (CDCSIM  for  CDC
and  UNIVAC SIMULA, IBMSIM for IBM SIMULA).  SIMULA programs
should have file name extension SIM, which is recognized  by
the  COMPIL  cusp  and  by  LINK-10.   A  SIMULA  program is
compiled, linked and run in the same  way  as  any  standard
language  processor,  e  g  FORTRAN,  by  using the commands
COMPILE, DEBUG, LOAD or EXECUTE.  The SIMULA  system  has  a
powerful  debugging  system, SIMDDT, which is loaded via the
DEBUG command at program start, on errors or via a C-REENTER
sequence  at  any  point  during  a program run.  No special
statements have to be introduced into the SIMULA text to use
SIMDDT.   Errors should be reported in writing to the SIMULA
maintenance group, FOA He1, 104 50 Stockholm 80, tel  631500
(08-631800), using the error report form shown in the SIMULA
Language Handbook, Part II, App I.  The failing program  and
its  data  should  be  kept available without change and its
protection code should make it possible  to  read  from  any
ppn, unless it is secret.  If the error can be isolated in a
smaller and simpler program, the smaller program  should  be
submitted.  [END OF SIMULA.HLP]
