In what condition you want to sort the files? Do you want to sort the files alone or you want to merge those sorted files?

If you have two VB files, or two FB files with the same LRECL, and you want to sort them on a common key, you can use a DFSORT job like this:

Code:

//S1    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN DD DSN=...  input file1
//       DD DSN=...  input file2
//SORTOUT DD DSN=...  output file
//SYSIN    DD    *
  SORT FIELDS=(p,m,f,a)
/*


where p,m,f,a is the starting position, length, format and sequence (ascending or descending) of the key, e.g. 5,4,CH,A.

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:
