There is a 80 byte sequential file that has to be sorted on the first 10 chars.However the added requirement is that when a record has all spaces in the first 10 positions then we have to use the last 10 positions instead as the sort criteria as alternate key.
Please let me know if there is a sort card we can write for this requirement.

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 (FB/80)
//SORTOUT DD DSN=...  output file (FB/80)
//SYSIN    DD    *
  INREC IFTHEN=(WHEN=INIT,OVERLAY=(81:1,10)),
        IFTHEN=(WHEN=(1,10,CH,EQ,C' '),OVERLAY=(81:71,10))
  SORT FIELDS=(81,10,CH,A)
  OUTREC BUILD=(1,80)
