Hi,

This is my first post in here!

I want to limit the number of registers copied in my sort!
For Example: The archive in (Sortin) has 50 registers and my archive out (sortout) must have the fisrt 20.

Thanks.
I'm Brazilian Guy! Sorry for english!

Paulo,

If you want to sort the records and output the first 20 sorted records, you can use this DFSORT job:

Code:

//S1    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN DD DSN=...  input file
//SORTOUT DD DSN=...  output file
//SYSIN    DD    *
  SORT FIELDS=(p,m,f,s)
  OUTFIL ENDREC=20
/*


p,m,f,s is the starting position, length, format and sequence, e.g. 1,10,CH,A

If you just want to get the first 20 records in the input file, you can use this DFSORT job:

Code:

//S2    EXEC  PGM=ICEMAN
//SYSOUT    DD  SYSOUT=*
//SORTIN DD DSN=...  input file
//SORTOUT DD DSN=...  output file
//SYSIN    DD    *
  OPTION COPY,STOPAFT=20
/*


If you want to do something else, please explain in more detail what you want to do and show an example of your input records and expected output records.

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:
