I don't know anything about ROUTINE_NAMES (expect that it is probably
not a good idea to use it if it is undocumented), but to get help
on system variables you can do this:

IDL> Help, /System_Variables

If you want help on a structure, you can do something like this:

IDL> Help, !Version, /Structure

I once spent a three days using a dictionary to find all the
undocumented procedures and functions that started with the letter A:

IDL> aardvark
IDL> aardwolf
IDL> aargu
IDL> aba

Etc.

I didn't find any, but whose to say they don't exist. I got half-way
through running through the whole list as functions before I
decided to leave the rest of the dictionary for a graduate
student project. :-)

Cheers,

David
