What's wrong with IDL_Init(), IDL_ExecuteStr() and IDL_Cleanup()?
You wouldn't expect RSI to use their competitor's name in their
own routines, would you?

Look at "Introduction to Callable IDL" and "Using Callable IDL under
Unix and VMS" in the External Development Guide (among the "Other
Online Books in the online help). There's a section on Fortran
use as well.
