you say tha half a million records go thru this monthly?
what is the concern then of creating a value of zero vs leaving a CUMM element 
null?
it would seem highly unlikely that not a single record you process has no value.
just element the tests for null that only stop a single addition and are not 
truely conditional.

Subject: [U2] Is this worth rewriting?

This is some old code that I didn't write, so please don't use it for
anything profitable ... 

The proposal to the group is: Due to the repeated references deep into
the PARMS tables, if this were rewritten to reference these locations as
few times as possible, IN YOUR OPINION, would there be a significant
improvement in the performance of this subroutine?

All in favor of rewrite, say AYE

All opposed, say NAY

 

(I'm testing some U2UG-Denver skills)

MONTHLY.USAGE:
       CM=MONTH+LY.CNT

       FOR M=1 TO 12

         IF PARMS(12)<101,CM>#'' OR PARMS(12)<133,CM>#'' OR
PARMS(12)<134,CM>#'' THEN

 

           CUM(M)=PARMS(12)<101,CM>+PARMS(12)<133,CM>+PARMS(12)<134,CM>

         END

         IF PARMS(7)<100,CM>#'' OR PARMS(7)<101,CM>#'' OR
PARMS(7)<102,CM>#'' THEN

 

           IF PARMS(7)<100,CM>#'' THEN CUMO(M)=CUMO(M)+PARMS(7)<100,CM>
ELSE

             CUMO(M)=CUMO(M)+PARMS(12)<101,CM>

           END

           IF PARMS(7)<101,CM>#'' THEN CUMO(M)=CUMO(M)+PARMS(7)<101,CM>
ELSE

             CUMO(M)=CUMO(M)+PARMS(12)<133,CM>

           END

           IF PARMS(7)<102,CM>#'' THEN CUMO(M)=CUMO(M)+PARMS(7)<102,CM>
ELSE

             CUMO(M)=CUMO(M)+PARMS(12)<134,CM>

           END

         END

         CM=CM-1; IF CM=0 THEN CM=24

       NEXT M

       RETURN
