vkumard,
Here's one way to do it with DFSORT/ICETOOL. I assumed your input files have RECFM=FB and LRECL=80, and there's nothing in the files that can identify the record to which each file belongs.
| Code: |
//S1 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN1 DD DSN=... input file1 (FB/80)
//IN2 DD DSN=... input file2 (FB/80)
//IN3 DD DSN=... input file3 (FB/80)
//T1 DD DSN=&&T1,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(,PASS)
//T2 DD DSN=&&T2,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(,PASS)
//T3 DD DSN=&&T3,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(,PASS)
//TOOLIN DD *
COPY FROM(IN1) TO(T1) USING(CTL1)
COPY FROM(IN2) TO(T2) USING(CTL1)
COPY FROM(IN3) TO(T3) USING(CTL1)
/*
//CTL1CNTL DD *
INREC OVERLAY=(81:SEQNUM,3,ZD)
/*
//S2 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTDIAG DD DUMMY
//SYSUDUMP DD SYSOUT=*
//SORTIN01 DD DSN=&&T1,DISP=(OLD,PASS)
//SORTIN02 DD DSN=&&T2,DISP=(OLD,PASS)
//SORTIN03 DD DSN=&&T3,DISP=(OLD,PASS)
//SORTOUT DD DSN=... output file (FB/80)
//SYSIN DD *
OPTION EQUALS
MERGE FIELDS=(81,3,CH,A)
OUTREC BUILD=(1,80)
