Hi ,

I am trying to split the value stored in comp-3 (WS-AB)(6 DIGITS) to another field which is also declared as comp-3(WS-B)
Here is my record structure.


Code:

01  REC.
   02  FILLER PIC  X(41)
   02  WS-AB  PIC  9(6) COMP-3 value 029999
   02  FILLER PIC  X(31)
   02  WS-B   PIC  9(7) COMP-3.
   02  FILLER PIC  X(8).

//STEP01W  EXEC PGM=SORT
//SORTIN   DD DSN=A.B.C,DISP=SHR
//SORTOUT  DD DSN=A.BC.SORTED,
//             DISP=(NEW,CATLG,DELETE),DCB=(RECFM=FB,LRECL=88,BLKSIZE=0),
//             SPACE=(CYL,(10,10),RLSE)
//SORTWK04 DD DISP=(NEW,DELETE,DELETE),SPACE=(CYL,(10,50)),
//            UNIT=SYSDA
//SORTWK05 DD DISP=(NEW,DELETE,DELETE),SPACE=(CYL,(10,50)),
//            UNIT=SYSDA
//SORTWK06 DD DISP=(NEW,DELETE,DELETE),SPACE=(CYL,(10,50)),
//            UNIT=SYSDA
//SYSIN    DD *
      SORT FIELDS=COPY
      OUTREC OVERLAY=(77:42,4,PD,TO=ZD,LENGTH=4)
//SYSPRINT DD SYSOUT=*
//SYSOUT DD SYSOUT=*


i am trying to MOVE last 4 digits from WS-AB to WS-B .I tried the above code , it works to see the value in FILE-AID only
when i changed the declaration from COMP-3 to numeric in record structure for the field (WS-B) (i,e) PIC 9(4).
can any one help me to see the same value without changing declaration?

The most-used way would probably be to multiply by 10 and then divide by 10. The first truncates the leading digit, the second corrects the scale of the field.

Here's a way without mathematics:

Code:
  INREC OVERLAY=(77:42,4,PD,TO=ZD,LENGTH=4,
                 77:77,4,ZD,TO=PD,LENGTH=4)


This works in-place because the length of the packed field is the same as the number of digits required, otherwise it would need to extend the record this way, and the calculation may turn out better (it would have to be tested, and depend on FB vs VB, lengths, size of file, which way the prevailing wind blows at your site, etc).
