Hi, I'd like to add 1 to a numeric field in a file.
From the example below, obviously column 5 I'd like to convert
to 1, 2, 3, 4.

How can I do this with SORT ?

Code:
//SORTIN   DD *             
XXX 0 TOM                   
AAA 1 BOB                   
BBB 2 JOE                   
CCC 3 FRANK                 
/*                         
//SORTOUT  DD SYSOUT=*     
//SYSIN    DD *             
  SORT FIELDS=COPY         
  INREC ...
/*

tcurrier,

Assuming the field is just 1 byte use the following DFSORT JCL
Code:

//STEP0100 EXEC PGM=SORT                       
//SYSOUT   DD SYSOUT=*                         
//SORTIN   DD *                               
----+----1----+----2----+----3----+----4----+--
XXX 0 TOM                                     
AAA 1 BOB                                     
BBB 2 JOE                                     
CCC 3 FRANK                                   
//SORTOUT  DD SYSOUT=*                         
//SYSIN    DD *                               
  SORT FIELDS=COPY                             
  INREC OVERLAY=(5:+1,ADD,5,1,ZD,EDIT=(T))     
//*

Thanks, Kolusu...

Pardon my ignorance, as I should be able to figure this out, but
what if the field to be added to is 5 bytes instead of 1 ?

Code:
//SORTIN   DD *   
XXX 00889 TOM     
AAA 01099 BOB     
BBB 02228 JOE     
CCC 09999 FRANK   
/*

tcurrier,

Simply change the length to 5 in the INREC statement. Assuming your data starts at pos 5 for a length of 5 use the following INREC

Code:

INREC OVERLAY=(5:+1,ADD,5,5,ZD,EDIT=(TTTTT))


Generic example
Code:


INREC OVERLAY=(P1:Constant,Function,P2,M,F,O1)

P1       = Position of the field where the result needs to be
Constant = Constant value to be added or subtracted ex: +1 or -12
Function = Function to be used (ADD, SUB, DIV, MUL ...)
P2       = Position of the input field to used with the function
M        = Length of the input field i.e. P2   
F        = Format of the input field ( ZD, PD, BI, FI, UFF, SFF ...)
O1       = Format of the output field
