Hi Buddy,

In Spring 2020, IBM updated RPG to allow a variable on KDS, which can be enabled via PTFs.  More info here: https://www.geeksforgeeks.org/how-to-increase-heap-size-in-java-virtual-machine/

If you do not (or cannot) install that update, or need to compile your program for tgtrls(v7r2m0) or older, then you'll need to use a value (not just definition) that's known at compile time.

Good Day All,

I am trying to make the following stmt work. I have never used a 2nd parm with %KDS, so new territory.

  Setll %KDS(KeyWSZ:KeyCnt) WSEQZONE;

When I use the variable KeyCnt for the 2nd parm in %KDS , I get the error below.

When I substitute the literal 2 for KeyCnt, it compiles fine.
    Setll %KDS(KeyWSZ:2) WSEQZONE;

Cause . . . . . : The second parameter for %KDS must be a numeric value with zero decimal positions known at compile-time. In addition,
the value must not be greater than the number of subfields in the data structure specified as the first parameter for %KDS. The operation is ignored.

not sure if the actual value has to be known at compile time or just the definition. Tried both. I'm guessing since the ibm example
below did not specify a value, that just the dcl is fine.

this is the DS

    DCL-DS KeyWSZ;
           WhseWS Like(WSWhse);
           ZoneWS Like(WSZone);
           RowWS Like(WSRow);
       END-DS;

this is the dcl for KeyCnt.

  DCL-S KeyCnt Int(10:0) inz(2);

This is from the ibm website

D numKeys          s            10i 0 ...          // The number of keys can be a constant         chain %kds(custRecKeys : 2) custRec;         // The number of keys can be a variable or an expression         numKeys = 1;         chain %kds(custRecKeys : numKeys) custRec;         chain %kds(custRecKeys : numKeys + 1) custRec;
