Say I have two words,
CURRENT DS F
SUM DS F
I want to add CURRENT to SUM, but most of the time CURRENT will be zero.
CURRENT and SUM are not adjacent (different data lines)
Which is best
L Rx,CURRENT
A Rx,SUM
ST Rx,SUM
or
L Rx,CURRENT
LTR Rx,Rx
JZ SKIP
A Rx,SUM
ST Rx,SUM
SKIP DS 0H
How about:
L Rx,CURRENT
LAA R0,Rx,SUM
if you have z196 or later machine

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.
I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
