I have 2 questions.

a) I need an RPG program I have written to be able to tell who is using
it. In other words I need to retrieve the program callers userid. Is
there an API I can use to do this? or a CL command? or ?

b) The second question stems from the first. I say I have written an RPG
program, I have actually started on my second this morning. I am
teaching my self RPG through the help of Judy Yaeger's book Programming
in RPG/400 second edition. It has been a good book to start but I am
ready for and RPG advanced features book or resource of some kind. I am
curious what book(s) are the essential RPG programmers reference books.
Do you just use the IBM RPG books that come on the softcopy CD-ROM or is
there a second party book that if you are going to be an RPG programmer
you gotta have. 

As usual thanks for sharing your wisdom. It is greatly appreciated.
