RE: How to read and or statement

That wouldn't work because it would keep on looping as long as the second when passed, totally ignoring the first part of the AND condition.

Subject: RE: How to read and or statement

I wouldn't let the difference between IF and WHEN stand in the way of the
approach Scott uses (which happens to match what I tend to do).

I would simply put in another WHEN with like actions.  If the actions are
more than a few statements, then I'd proceduralize or at least make SUBR of
them.

I would probably do it that way as well, but it is not exactly the
same, since the first statement contained a WHEN.

If *INKF were off or both condition1 and condition2 were on, the next
WHEN statement would be executed.

Shrug... I wrote complex logical expressions in RPG III..  I just

didn't

intermix AND/OR the way David demonstrated.

I'd do something more like this:

C     *INKF         IFEQ      *ON
C     CONDITION1    IFEQ      FALSE
C     CONDITION2    OREQ      FALSE
...
C                   ENDIF
C                   ENDIF

That way, I didn't get confused by which one took precedence...
starting a new IFxx statemnet controlled my precidence.

But I much prefer having parenthesis, and I can't see why someone

would

use the godawful IFxx/ORxx/ANDxx stuff today.

But many millions were debugged!

giving up the old style.

Why not try the code, just as you want it (except change the if to

a

when), and see if it works?
