SETUP:

For MS-DOS:	Running PERCH under DOS needs no special setup.

For MS-Win 3.1: Move all *.DLL and *.VBX to your MS-Windows/
		System directory.

Add following line to your system.ini:
		device=dosxnt.386 (incl. full path)
and restart MS-Windows before starting the PERCH-Shell (WPERCH.EXE).

     NOTE:     PERCH programs will not run under Windows 3.1 without this 
    	       driver declared in the SYSTEM.INI.

	**** TIPS ****

1. When you have problems to start any PERCH-Program, check your memory 
   resources. Usually the uploading the DOS-extender (needs 1.2 MB) fails 
   when there is a lack of memory. Try to free up as much memory as possible.
   Under Windows, enlarge the size of Windows swap file (in the Control Panel 
   under the 386 enhanced icon). 

There is no bug-free software. In order to improve PERCH we greatly appreciate 
all kind of comments, critics and bug-reports from you.

Possible MS-DOS Extender Conficts
---------------------------------

Several Microsoft language products provide 32-bit
MS-DOS-extended tools that use the Microsoft DOSXNT MS-DOS
Extender. The version of DOSXNT used by Microsoft PowerStation
FORTRAN version 1.0 is not compatible with the version used by
Microsoft MASM version 6.1.

To ensure that all MS-DOS-extended tools run successfully, it
is recommended that you install each language product in a
separate directory and that you leave each version of
DOSXNT.EXE in the subdirectory that contains the tools it
supports. This allows each MS-DOS-extended tool to locate the
appropriate version of DOSXNT.EXE. Make sure that the PATH
environment variable specifies the directory in which you
installed FORTRAN PowerStation version 1.0 before the directory
that contains MASM 6.1. This ensures that you can run the latest
versions of tools that are in common to both products.

If you install both FORTRAN PowerStation and MASM 6.1 in one
directory, you will not be able to run MASM.EXE and ML.EXE from
the command line. However, you will be able to run these tools as
commands executed by NMAKE.
