>>I used to do way more programming in C/C++, and for a real eye opener one time, we ran lint (a C utility) on our code.

Hi Bruce,

I'd first assign SYS(0) to a variable. This would eliminate three function calls in the above. Further, I'd simplify it to:

lcuser = SYS(0)
lcuser = ALLTRIM(SUBSTR(lcuser, ATC('#', lcuser) + 1))

There's no need to provide a length for SUBSTR() since it will take whatever remains of the string if it isn't provided.
