Hi all

I'd like to know if/how it is possible to use DFSORT/ICETOOL to just determine if a dataset is sorted or not, and then give a suitable returncode. I'd like to invoke the sort from JCL.

regards

Killer

Sort the input file in the order you expect it be sorted and then compare the original file and sorted file using SUPERC. SUPERC reports differences even if the order of the records are different.
If RC=1, then the input file was not sorted, if RC=0, then the input file was sorted.

Killer,

If the file is sorted you will have RC=0, if not RC=16
Code:

//STEP0001 EXEC PGM=ICEMAN
//SYSOUT   DD SYSOUT=*     
//SORTOUT  DD SYSOUT=*     
//SORTIN01 DD *           
02                         
03                         
01                         
/*                         
//SYSIN DD *               
  MERGE FIELDS=(1,2,ZD,A) 
/*
