ancient dos program

[Dave]

i have an ancient dos program, written in fortran which uses a pharlap dos
extender. it runs ok on win2k, but fails with a stack fault on xp. i have
tried dozens of variations on the compatibility settings and memory settings
with no help. anything else to try? something in config.nt??

It might be making calls to devices that are not emulated by WinXP's 16-bit
environment. In other words, it may simply be not compatible with Windows
XP. If you want to run it you might have to dedicate a computer running
Windows 2000.

Try JP Software's 4NT or Take Command programs - one might give you what
you're looking for. www.jpsoft.com

Do you still have the Fortran source code? If so, you can recompile
with a free compiler such as OpenWatcom, g77 (my default suggestion),
g95, or gfortran. I suggest experimenting with these, and if you still
have problems, post the details to comp.lang.fortran .

i don't have it, we are trying to find the contractor who does. ie appears
that this is a known problem with some old version of lahey's fortran tools.
