Calling Fortran program [message #2188]

Hi

I have to call a Fortran program that returns a vector. The IDL function CALL_EXTERNAL
allows to return a scalar value only. So it seems I have to use LINKIMAGE.

Is there anybody who knows how to use LINKIMAGE in particular who has any idea how to
pass a vector to IDL using LINKIMAGE ? ( I am using a SUN and I studied the manual for
dlopen() already. This was not very helpful.)

Thanks in advance ....

I find the documentation in the idl/misc/dynamic_link directory to be
somewhat more accurate than the idl-fortran faq file. Things reagrding
FORTRAN and IDL may have changed recently. In that directory, they
have examples of how to pass and return data from and to FORTRAN without
using any C (non-standard FORTRAN extensions needed for this).

Looking at this I just learned that IDL can return arrays instead of
just scalars.
