Kolusu,

Thanks for your quick response

The parameters are:
LRECL=640 and the field size is 8 bytes(S9(10)V9(5) comp-3).
Position of the field=12.

Rasprasads,

There are 2 ways of changing the sign. you can use a change command to change the sign on the last byte of the field in question or you can use horizontal math function (add,sub,mul,div) to change the sign.

Choose whichever you like

Code:

//STEP0100 EXEC PGM=SORT
//*                                           
//SYSOUT   DD  SYSOUT=*                       
//SORTIN   DD  DSN=YOUR INPUT FILE,     
//             DISP=SHR                       
//SORTOUT  DD  DSN=YOUR OUTPUT FILE,           
//             DISP=(NEW,CATLG,DELETE),       
//             UNIT=SYSDA,                     
//             SPACE=(CYL,(X,Y),RLSE)       
//SYSIN    DD  *                               
  SORT FIELDS=COPY                                           
  INREC FIELDS=(1,18,                   
                19,1,CHANGE=(1,X'1C',X'1D',X'1D',X'1C',
                             X'2C',X'2D',X'2D',X'2C',X'3C',X'3D',X'3D',X'3C',
                             X'4C',X'4D',X'4D',X'4C',X'5C',X'5D',X'5D',X'5C',
                             X'6C',X'6D',X'6D',X'6C',X'7C',X'7D',X'7D',X'7C',
                             X'8C',X'8D',X'8D',X'8C',X'9C',X'9D',X'9D',X'9C'),
                     NOMATCH=(19,1),
                20,621)                   
/*


Method:2
Code:

//STEP0100 EXEC PGM=SORT
//*                                           
//SYSOUT   DD  SYSOUT=*                       
//SORTIN   DD  DSN=YOUR INPUT FILE,     
//             DISP=SHR                       
//SORTOUT  DD  DSN=YOUR OUTPUT FILE,           
//             DISP=(NEW,CATLG,DELETE),       
//             UNIT=SYSDA,                     
//             SPACE=(CYL,(X,Y),RLSE)       
//SYSIN    DD  *                               
  SORT FIELDS=COPY
  INREC FIELDS=(1,11,                       $ FIRST 11 BYTES
               -1,MUL,12,8,PD,PD,LENGTH=8,  $ MULTIPLY WITH -1 FOR PD
                20,621)                     $ REST OF THE FIELDS
/*


Hope this helps...

cheers

Kolusu,
Thanks a lot for your patience and help...
I tried the second solution using arithmetic function MUL and it worked fine...

Thanks
