Our code is a bit of a hybrid of lots of legacy things. It is a very large
body of code for accessing some data files and automatically retrieving said
data from a remote database. This is why it has all the unixism's in it.
In fact, cygwin can actually compile all of our code and everything works
with Windows. Its just interfacing with IDL that is causing me problems.

Getting Visual Studio to compile everything will be very difficult, but
not impossible so I may do it after all.

Is there a good reference on the difference between DLM and CALL_EXTERNAL?
Someone told us to make a DLM and we did so I never researched the possibility
of doing a CALL_EXTERNAL. Possibly I could convert my code from DLM to a
CALL_EXTERNAL to keep the Windows people happy?

Does anyone know if GDL supports either of these mechanisms for using
external code?

Thanks,
Joey
