Hi all,

Please let us know if any body aware the sort utility options to convert Zone Decimal (Positive Value) to Zoned Decimal (Negative Value).

For eg: Amount field is 21.69 then internally in mainframe it is stored as



Positive Value is stored as : FFFFFFFFFFF

00000002169

Negative value is stored as : FFFFFFFFFFD

00000002169



We need the Sort utility function to convert the X'F' to X'D' ( Last half byte), hence the Zoned decimal amount field will be converted to Negative amount.

Here's a DFSORT job that will change a positive value (C or F sign) to a negative value (D sign), but leave a negative value (D sign) as is. I assumed your 11-byte ZD value started in position 21 but you can change the job appropriately for other starting positions.

Code:

//S1    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN DD DSN=...  input file
//SORTOUT DD DSN=...  output file
//SYSIN    DD    *
   OPTION COPY
* If ZD value >= 0, change sign to minus (D).
   INREC IFTHEN=(WHEN=(21,11,ZD,GE,+0),
      OVERLAY=(21:21,11,ZD,MUL,-1,TO=ZD,LENGTH=11))
