Re: Clear entire field vs substring

[Vern Hamberg <vhamberg@xxxxxxxxxxx>]

Man, this is a lot of work when the system will help you so much! As has 
been said in this thread - oooh! that rhymes! - an EVAL basically does a 
set and pad, probably - Chuck's reply suggests this. I mean, Albert is 
not extracting values from the middle of the workfield, is he?

An = is an implied EVAL - NOT a MOVE.

Hey, I love to get complicated, too - but I'm learning!!

Vern

If workfield is varying-length, the system knows
