Hi,
I would like to replace certain position with a particular value for all the records in a file. For example, I need to replace the value 'XX' which is present in postion 1:2, with the value '20' for all records in my input file. How could I do that using a JCL?
Thanks,
Perumal.N.K.

If you want to replace 'XX' in positions 1-2 with '20' and leave records without 'XX" as is, you can use a DFSORT job like the following:
SORTOUT would have:
If you're not familiar with DFSORT and DFSORT's ICETOOL, I'd suggest reading through "z/OS DFSORT: Getting Started". It's an excellent tutorial, with lots of examples, that will show you how to use DFSORT, DFSORT's ICETOOL and DFSORT Symbols. You can access it online, along with all of the other DFSORT books, from:
www.ibm.com/servers/storage/support/sof ... tmpub.html
Code: Select all
//S1 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTIN DD *
XX RECORD 01
YY RECORD 02
XX RECORD 03
ZZ RECORD 04
//SORTOUT DD SYSOUT=*
//SYSIN DD *
OPTION COPY
INREC IFTHEN=(WHEN=(1,2,CH,EQ,C'XX'),OVERLAY=(1:C'20'))
/*
Code: Select all
20 RECORD 01
YY RECORD 02
20 RECORD 03
ZZ RECORD 04
