Re: purpose of Z-ADD?

Disregarding performance considerations, as long as you are initializing a
field with *ZEROS it is irrelevant whether MOVE or Z-ADD is used...

However, don't forget that Z-ADD respects decimal positions in the target
fields while MOVE does not.

Example:

If you have a field named WORK which is defined as 15.5 (15 positions with 5
decimals),

C Z-ADD5 WORK

gives the result of 5.0000

while

C MOVE 5 WORK

gives the result of .00005

so, Z_ADD served to move a numeric field with one machin OP.
