You should have a look at catalog_db from our library.

The output you like to have you'll see by clicking on one of the database
icons
The trick is to call idl to find the necessary info itselfs.

Yes call idl, see above.

I'm not quite sure what you want to do, but if the question is just how
IDL finds procedures and functions to compile, the following article
will tell you:
http://www.dfanning.com/tips/namefiles.html
If you want to determine the directory in which a function or procedure
was found:
http://www.dfanning.com/documents/programs.html#PROGRAMROOTD IR
The FILE_WHICH() function is also useful.
In general, you always want to put IDL program files into the IDL path.
Good luck,
Benjamin
