I need to put a header record (all zeroes) in a VSAM file (Fixed length; LRECL=41)...I tried EXEC PGM=IEBDG but found that its only for sequential files..How to achieve this? I am wondering if we can use SORT utility for this??

Here's one way to do this with DFSORT's ICETOOL:

Code:

//S1    EXEC  PGM=ICETOOL
//TOOLMSG   DD  SYSOUT=*
//DFSMSG    DD  SYSOUT=*
//IN DD DSN=... VSAM file
//T1 DD DSN=&&T1,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(,PASS)
//T2 DD DSN=&&T2,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(,PASS)
//CON DD DSN=*.T1,VOL=REF=*.T1,DISP=(OLD,PASS)
//    DD DSN=*.T2,VOL=REF=*.T2,DISP=(OLD,PASS)
//OUT DD DSN=... VSAM file
//TOOLIN DD *
* IN->T1: Create a header record with 41 zeros in seq file T1
* IN->T2: Copy the VSAM records to seq file T2
  COPY FROM(IN) USING(CTL1)
* T1/T2 -> OUT:  Copy the header record and original records
* from the seq files to the VSAM file
  COPY FROM(CON) TO(OUT)
/*
//CTL1CNTL DD *
  OUTFIL FNAMES=T1,ENDREC=1,OUTREC=(41Z)
  OUTFIL FNAMES=T2
/*
