So that rules out the possibility of having a program file full of SUBs and putting small wrapper functions in other programs that call those SUBs.

Another quickie: Is there a way to list the commands/keywords/functions in any given LEX file? I faintly recall seeing some way to do that, but can't recall what it was.

#1 - I'm not sure if it's what you're looking for, but look at the MYSUBS program in Joe's Titan File Collection, available here.

#2 - The file HLPLEX is just what you're looking for. There are several commands included, but the simplest and most common form is "HELPF MYLEX" which will display all the keywords (and associated argument types) found in the LEX file MYLEX.

HLPLEX is in the OLDP, but note there is no E in the beginning of the filename HLPLEX.
