Thanks for the information. The IDL internals manual is available
free from RSI, if anyone else is in need of a copy.

We have a copy (Version 2.0.7), sent to us by RSI. It is a thin,
softcover manual describing the internal data structures and subroutines
used by IDL.
If you are writing C functions to be compiled and linked with IDL, then this
manual is an absolute necessity. To do static linking, of course, you
would need the object files (_not_ normally supplied by RSI), and I understand
that dynamic linking (using the IDL LINKIMAGE facility) is possible only
on the VAX/VMS version. We used it to add a graphics device driver to the
default VMS setup and encountered no significant problems.
Depending on whether this sort of thing is what you want to do, the
Internals Manual is either mandatory or utterly useless. For an
internals manual, though, it is fairly well written, with useful
fragments of example code.
Hope this helps.
