From that links-page:

Libwin 0.1.1 by Rich Dawe. The aim of the library is to allow DJGPP 
programs to make better use of the Windows environment. Thus, it 
includes clipboard access, user information, version information,
low-level device driver (VxD), DOS box and virtual machine titling and 
registry functionality. GPL.

I remember seeing this lib, but I don't understand what good it does to
me. The things mentioned in this description don't seem useful for my 
problem. (But I may be wrong of course).

Let me give some more details of the type of problems we have regarding 
interfacing with a DJGPP program:

Our DJGPP program is a simulation-program for a factory. Basically, this 
program simulates the behaviour of that factory.
You provide input, and some control-parameters, and the simulation program
produces results.

The simulation program should cooperate with MS-Windows apps, like Excel
and Access. There are 2 types of problems here:

1) Excel should provide input and control-parameters, then start the
   simulation, then after execution read the results and analyse them.
   Excel functions as a front-end before our program in this setup.

   something like 'system("simulation.exe")' will probably work here
   as suggested by Eli Zaretskii (thanks !)

2) The DJGPP simulation-program needs a MS-win app to do some
   calculations for it. For example, we need to lookup a value from a large
   MS-Access data-base (or from an Excel spread-sheet).

   How to do this is not clear to me. Can I use Libwin for this purpose ?
