Calling FORTRAN routines from IDL [message #799]

I'm a new user of IDL, so I'm soliciting HELP!!! I'm attempting
to call FORTRAN routines from IDL using the 'call_external' function.
In the call, I'm passing a file name to the routine. Basically I
have a FORTRAN front-end to the FORTRAN routine. The FORTRAN
front-end passes the parameters by 'value' not reference. The
IDL commands follow. Note that 'hdr.txt' is my file name.

IDL> a=bytarr(1)
IDL> a(0) = 1
IDL> tmp=call_external('readhdr.so', '_readhdr_', 'hdr.txt', value=a)
....then I receive garbage.

I've also tried sending the file name by reference and received the
same type of results.

Has anyone experienced this type of problem?? Is there a solution or
easier method for accessing FORTRAN routines from IDL?

Thanks for all responses,
