Re: How to read and or statement

Hi, David:

You can always use extra parentheses, even if they are "redundant" -- to
ensure the compiler knows exactly what you want.

So, for example, you could code something like this:

WHEN (*INKF *AND ((COND1 = FALSE) *OR (COND2 = FALSE)))

and that way, there should be no doubt (by the compiler or any
subsequent human readers) of what is intended.

When in doubt, parenthesize.

Hope that helps,

Mark S. Waterbury

Here is a clip from the V5R4 RPG Reference

Condition for the DOUxx, DOWxx, IFxx, and WHENxx operations.
The ANDxx operation has higher precedence than the ORxx operation.

Subject: How to read and or statement

Consider this code :

C *INKF WHENEQ *ON
C CONDITION1 ANDEQ FALSE

*If I add :
C CONDITION2 OREQ FALSE


I think this now means :

IF (*INKF AND CONDITION1=FALSE) OR (CONDITION2=FALSE)

But I want :
IF *INKF AND (CONDITION1=FALSE OR CONDITION2=FALSE)

Which is right?

Thanks
