Sigh. Why didn't you say what you actually wanted in your first post or subsequent posts? It's not clear how what you've said you want so far has to do with your statement "i am comparing date fields".
However, if you want the current date - 60 days in the form 'mmddyyyy', you can use these DFSORT statements:
//S1 EXEC PGM=ICEMAN
//SYSOUT DD SYSOUT=*
//SORTIN DD *
//SORTOUT DD DSN=... output file (FB/8)
//SYSIN DD *
If that isn't what you want, then explain in detail
exactly what it is you want to do.
