There are several ways to do this with DFSORT, but the easiest is to use DFSORT's SPLIT1R=n option as follows. The first 100000 records will be written to OUT1 and the remaining records will be written to OUT2. //S1 EXEC PGM=ICEMAN //SYSOUT DD SYSOUT=* //SORTIN DD DSN=... input file //OUT1 DD DSN=... output file1 //OUT2 DD DSN=... output file2 //SYSIN DD * OPTION COPY OUTFIL SPLIT1R=100000,FNAMES=(OUT1,OUT2) /* Frank Yaeger - DFSORT Development Team (IBM) - [EMAIL PROTECTED] Specialties: PARSE, JFY, SQZ, ICETOOL, IFTHEN, OVERLAY, Symbols, Migration => DFSORT/MVS is on the Web at http://www.ibm.com/storage/dfsort/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
