Yes, you're right about that. I guess you could *almost* convert
an f77 program to IDL through some simple search-and-replace
macros/functions in emacs, but then you'd essentially have a
slow f77 program, with f77 programming style but with IDL
syntax/semantics. Much better then, to either use call_external
fortran subroutines, or to use IDL as an RPC server from f77. Both
methods allow mixing of f77 for speed and IDL for e.g., plotting.
I don't program in Fortran so don't take the above statement
about f77->IDL by search-and-replace statements too seriously.

Going from C -> IDL might be impossible unles somebody wanted
to handle pointers anbd pinters to pointers etc.
But Fortran -> IDL should be easier. At least, i can think of
anything in F77 that can't be done in IDL. Optimizing the
IDL code would be the hard part if you wanted to make an efficient
translation.

Indeed, but I wouldn't spend much time searching for one,
it's quite unlikely that any such creature exists.
Going from a "low-level" to a "high-level" language is not
an easy task to do automatically -- it's just about impossible.
Going the other way, from IDL->C or IDL->FORTRAN is feasible,
though, but I haven't heard about any program that actually does
it.
