hi,
I have a question, how can I speify the order of records in an output file,e.g. a file contains many records, which is formatted like follow,

Code:

name       currency     currency-wanted
11**         cad                 usd
11**         cad                 usd
11**         usd                 usd
11**         usd                 usd
11**         eur                 usd
11**         jpy                 usd
22**         aud                 eur
22**         aud                 eur
22**         eur                 eur
22**         usd                 eur
22**         usd                 eur


the result I want is that , the records contain same name should be collocated together and those whose "currency" field equals to "currency-wanted" must be put at the end of them.So the output should be

Code:

name       currency     currency-wanted
11**         cad                 usd
11**         cad                 usd
11**         eur                 usd
11**         jpy                 usd
11**         usd                 usd
11**         usd                 usd
22**         aud                 eur
22**         aud                 eur
22**         usd                 eur
22**         usd                 eur
22**         eur                 eur


I am a new programmer, sorry for any various interpretations bringing to you...

thank you for help.

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'0')),
    IFTHEN=(WHEN=(14,3,CH,EQ,34,3,CH),OVERLAY=(81:C'1'))
  SORT FIELDS=(1,4,CH,A,81,1,CH,A),EQUALS
  OUTREC BUILD=(1,80)
/*


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:
