Hm, this sounds as if you are compiling in dos mode? In that case you
are probably running up against the 64Kb limitation. I think you will
need to compile McStas for 32 bit.

Anyway, I just got Rene Moeller to help me compile mcstas for Windows
95/NT. This is compiled as a 32bit console application, so there should
be no memory problems.

You can download it from this URL:

  http://ELU-ALF-2.risoe.dk/~elu-krni/mcstas/support/misc/mcstas.exe

To use it, you need to set the environment variable MCSTAS to point to
the "lib" subdirectory of the mcstas distribution, eg:

  set MCSTAS=C:\mcstas\lib

Let me know if it works so that I can make a proper Windows release of
McStas.
