Here's a DFSORT job that will do what you asked for. I assumed your input file has RECFM=FB and LRECL=80, but the job can be changed appropriately for other attributes:

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:C'1')),
    IFTHEN=(WHEN=(1,6,CH,EQ,C'HEADER'),OVERLAY=(81:C'0'))
  SORT FIELDS=(81,1,CH,A,1,6,CH,A)
  OUTREC BUILD=(1,80)
/*
