Don't forget CLEAR,.. but only for initialization to a fields' low value. I'm not sure of any differences except when using different sized fields. EVAL will fail upon truncation of fields where Z-ADD will not.

Subject: Z-ADD or Eval?
I am trying to use all Evals in my programming just because it is much easier to read and understand.
My question is, however, should I be converting Z-ADDs to Evals? I understand we use(d) Z-ADD
instead of MOVE because Z-ADD was more effiecient. We could of used MOVE, but we used Z-ADD.
Now, if I have a statement (and I do):
C 99 Z-ADD *ZERO EQSIZE
and I want to convert this to "modern" programming, should it become:
C If *IN99
C Z-Add *Zero EqSize
C EndIf
or should it become:
C If *IN99
C Eval EqSize = *Zero
C EndIf
Any comments on this are appreciated.
Regards,
Jim Langston
