I have an input file (NOT SORTED) that I want to set sequence numbers on, with a RESTART that comprises segemented fields. Consider the following input :


111 aaa 222 0000
111 bbb 222 0000
111 ccc 223 0000
111 ddd 224 0000
111 ddd 224 0000


as output I want :

111 aaa 222 0001
111 bbb 222 0002
111 ccc 223 0001
111 ddd 224 0001
111 ddd 224 0002


my problem is that I want to sort and overlay with SEQNUM with a RESTART on (1,3) and (9,3), but OVERLAY seems to want contiguous data.

So ... I can achive this using a control statement like :


INREC=() * reformat input to put the key fields together.
SORT FIELDS=(...)
OUTREC OVERLAY=( ... RESTART=(1,6) )

my problem is that I then have to reformat the output to put it back in the original format ... is there a more
elegant approach ....

I'm not quite sure what you're looking for, but how about this DFSORT job?

Code:

//S1    EXEC  PGM=ICEMAN                                           
//SYSOUT    DD  SYSOUT=*                                           
//SORTIN DD *                                                       
111 aaa 222 0000                                                   
111 bbb 222 0000                                                   
111 ccc 223 0000                                                   
111 ddd 224 0000                                                   
111 ddd 224 0000                                                   
//SORTOUT DD SYSOUT=*                                               
//SYSIN    DD    *                                                 
  INREC OVERLAY=(81:1,3,9,3)                                       
  SORT FIELDS=(1,3,CH,A,9,3,CH,A)                                   
  OUTREC IFOUTLEN=80,                                               
    IFTHEN=(WHEN=INIT,OVERLAY=(13:SEQNUM,4,ZD,RESTART=(81,6)))
