In my input file, there is a field having values of A, B, C or D etc of one char.
In my output file I want all A or B to be written as 'Y' and all C or D or rest to be written as 'N'.
Ex:
Input
1111 A
2222 B
3333 C
4444 D
5555 X
6666 Z

Output
1111 Y
2222 Y
3333 N
4444 N
5555 N
6666 N

Could anyone please suggest what should be sort card or how can i do it with Sort.

Thanks.

Here's a DFSORT job that will do what you asked for:

Code:

//S1    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN DD DSN=...  input file
//SORTOUT DD DSN=...  output file
//SYSIN    DD    *
  OPTION COPY
  INREC IFTHEN=(WHEN=(6,1,SS,EQ,C'A,B'),OVERLAY=(6:C'Y')),
        IFTHEN=(WHEN=NONE,OVERLAY=(6:C'N'))

Hey Thanks a ton for your quick response.

I used it, and got my work done.

Please let me know what does 'SS' mean in the following
WHEN=(164,1,SS,EQ,C'A,E,G,L,R,X,Y,Z')
OVERLAY=(164:C'Y')),
IFTHEN=(WHEN=NONE,OVERLAY=(164:C'N'))
and when=none means for the rest of values or something else.

Thanks in advance.

SS is substring comparison - see:

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/ICE1CA20/3.7.4?DT=20060615185603

WHEN=NONE means any record that did not satisfy the WHEN=(logexp) conditions.

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:
