In my opinion you are best to use C to wrap your Fortran functions as
dynamic linked modules (DLMs). Ronn Kling has a nice book which
introduces the concepts of DLM programming in IDL
(http://www.kilvarock.com/) but it assumes you are somewhat familiar with
some C. Calling Fortran functions from C is well discussed in the Sun
Workshop documents
( http://tulip.atm.ox.ac.uk/~rhskelto/documents/fortran/fortra n-C.pdf). I
don't think there are too many differences for Windows programming, but I
am not sure.
If you aren't feeling that brave, you can look through the examples of
'call_external' in the IDL external development guide. At least this will
avoid the writing of text files...
Cheers,
Randall
