                      PASCAL-XSC Demo INSTALL Documentation
                    -----------------------------------------


System Requirements:
                     Memory : 640kB conventional memory

                     Storage: Hard disk

                     CPU    : 100% compatible IBM PC/XT/AT or 386/486

                     DOS    : DOS version 3.3 or higher.

                     C      : Borland C++ Version 2.0 or higher


Installation of the PASCAL-XSC compiler:

       Unzip the file PXSCDEMO.ZIP with  the option -d.  The  Zip file
       contains the  directories PXSC\BIN  and PXSC\SYS  which will be
       created during unzip on your target drive.

       Install the Borland  C++ compiler system  as described in  your
       manual.  For  an error-free  PASCAL-XSC compilation  step it is
       necessary, that the C compiler is executable from any directory
       on your  system (set  the PATH  to your  Borland-C++ binaries).
       The PASCAL-XSC  compiler generates  a C  compiler call  for the
       large  model  library;  therefore  you  have  to install your C
       compiler with that option.

       Edit  your  AUTOEXEC.BAT  file  to  set  the  PATH  variable to
       <drive>:\PXSC\BIN where  drive is  the actual  drive containing
       the PASCAL-XSC system.

       Set the environment variable PXSC_SYS to the PASCAL-XSC  system
       path PXSC\SYS\.   Don't forget the  last backslash in  the path
       definition, i.e.  SET PXSC_SYS=C:\PXSC\SYS\ .

       Set the environment variable PXSC_EDIT to your favorite  editor
       you  want  to  use  during  PASCAL-XSC program development (for
       example SET PXSC_EDIT=C:\DOS\EDIT).

       After  reboot  you  can  start  the PASCAL-XSC compiler manager
       DXSC.EXE or MXSC.EXE which are self explanatory and then  start
       any compilation.

       The  file  STACKSZ.C  allows  you  to  increase or decrease the
       default stacksize of  the program to  be linked by  the Turbo C
       linker.    It  can  be  found  in  the  ..\SYS directory of the
       PASCAL-XSC system.

       Note: This  IBM/PC version  of the  PASCAL-XSC system  does not
             contain the  modules MVC_ARI  and MVCI_ARI  due to memory
             failure with the Borland C++ compiler.

       Demo restrictions : The demo version of the PASCAL-XSC compiler
                           contains  all   the  features   defined  in
                           "PASCAL-XSC    Language    Reference   with
                           Examples"  published  by   Springer-Verlag,
                           1992, ISBN  0-387-55137-9.   The amount  of
                           blocks (subroutines and/or WITH-statements)
                           is restricted  to 15  for each  compilation
                           unit.
