Greetings,

I hope this question hasn't already been answered elsewhere. I did the searches I could think of and didn't find anything.

I have an LRECRL=80 file in which I need to convert columns 50-56 to a packed field with a value of zero, but only if columns 50-56 contain spaces (i.e. x'40404040404040'). If the records don't contain spaces in these positions I don't want to change anything.

Here is an example:

[code:1:9b4c0ffb05]
4444444
0000000

Sterling price,

Try this JCL,

Code:

//STEP0100 EXEC PGM=SORT                                           
//SYSOUT   DD SYSOUT=*                                             
//SORTIN   DD DSN=your input dsn,
              DISP=SHR                           
//SORTOUT  DD DSN=YOUR OUTPUT DSN,
//            DISP=(NEW,CATLG,DELETE),
//            UNIT=SYSDA,
//            SPACE=(CYL,(1,1),RLSE)
//SYSIN    DD *                                                     
  SORT FIELDS=COPY                                                   
  OUTREC FIELDS=(1,49,                                               
                 50,7,CHANGE=(7,X'40404040404040',X'0000000000000C'),   
                 NOMATCH=(50,7),57,24)                               
/*                                                                 


Hope this helps...

Cheers

With z/OS DFSORT V1R5 PTF UQ95214 or DFSORT R14 PTF UQ95213 (Dec, 2004), you can also do this using the new IFTHEN and OVERLAY parameters as follows:

Code:

//S2    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN DD DSN=...  input file
//SORTOUT DD DSN=...  output file
//SYSIN    DD    *
  SORT FIELDS=COPY
  OUTREC IFTHEN=(WHEN=(50,7,CH,EQ,C' '),
     OVERLAY=(50:+0,TO=PD,LENGTH=7))
/*


IFTHEN is a lot more powerful then CHANGE.

For complete details on the new DFSORT and ICETOOL functions available with these PTFs, see:
