Sean,

The way you coded it, you created an array of 999 data structures, each one containing all the BTAMxx fields. If you want an array of BTAM fields, you need something like:

    D                 DS
    D BTAMXX
    D BTAM59                              LIKE(CMAM22) OVERLAY(BTAMXX:*NEXT)
    D BTAM01                              LIKE(CMAM01) OVERLAY(BTAMXX:*NEXT)
    D BTAM02                              LIKE(CMAM02) OVERLAY(BTAMXX:*NEXT)
      ...
    D BTAM                                LIKE(CMAM01) DIM(999) OVERLAY(BTAMXX)

(BTW: Is it correct that BTAM59 is the first field?)

As for the overflow: In the last iteration of the for loop, the counter has the value 999. After that iteration the counter is increased, but 1000 will not fit in a 3.0 field.

I saw a thread a while back that prompted me to convert my RPG III program to RPG IV to take advantage of some new features like ds array and the += operator.

So far, it is looking very good. I have a 999 element array and got data into the subfields. Now I want to output any of those elements that are not all zeros. Is there a shortcut? (Using V5R2)

     DBrnTotal         DS                  DIM(999) QUALIFIED
     D BTAM59                              LIKE(CMAM22) INZ(0)
     D BTAM01                              LIKE(CMAM01) INZ(0)
     D BTAM02                              LIKE(CMAM02) INZ(0)
     D BTAM03                              LIKE(CMAM03) INZ(0)
     D BTAM04                              LIKE(CMAM04) INZ(0)
     D BTAM05                              LIKE(CMAM05) INZ(0)
     D BTAM06                              LIKE(CMAM06) INZ(0)
     D BTAM07                              LIKE(CMAM07) INZ(0)
     D BTAM08                              LIKE(CMAM08) INZ(0)
     D BTAM09                              LIKE(CMAM09) INZ(0)
     D BTAM10                              LIKE(CMAM10) INZ(0)

... Many additions into the subfields as I accumulate totals

     /FREE
          For Brn = 1 TO 999;
            If BrnTotal(Brn) <> *ZERO;
              // DO STUFF WITH SUBFIELDS;
            EndIf;
          EndFor;
     /END-FREE

... All 999 records show up.

Any suggestions other than

If BrnTotal(Brn).BTAM59 <> 0 OR BrnTotal(Brn).BTAM01 <> 0 OR ... etc


P.S. Since I only have DIM(999) why did it not run with BRN as 3,0? I had it LIKE(my branch number field) but changed to 10I0 after the error. (Got "The target for a numeric operation is too small to hold the result" when it hit the For loop.)
