An assortment of 71B questions

[Dave Britten]

I was tinkering with user-defined functions last night, and it seems you can CALL a SUB from inside a function, but only within the program file that contains the function. 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.
