Hi all,

I am using the below sort card in one the steps in JCL.

SORT FIELDS=(1,10,CH,A)
OUTFIL REMOVECC,NODETAIL,
SECTIONS=(1,10,
TRAILER3=(1,10,X,COUNT=(M11,LENGTH=9)))

Its working fine when there are some records in Input but its giving one output record even when the input file is empty.

Output record

000000000
(Nine zeros at the position of count) Where as I would like to have the output as empty in above case.

I am new to SORT and would appreciate help on this.

-thanks
David P.

TRAILER3 is supposed to write a record even when the input file is empty.

You can easily eliminate that record when the count is all 0's with a DFSORT/ICETOOL job like this:

Code:

//S1    EXEC  PGM=ICETOOL
//TOOLMSG   DD  SYSOUT=*
//DFSMSG    DD  SYSOUT=*
//IN DD DSN=... input file
//T1 DD DSN=&&T1,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(,PASS)
//OUT DD DSN=...  output file
//TOOLIN   DD    *
SORT FROM(IN) USING(CTL1)
COPY FROM(T1) TO(OUT) USING(CTL2)
/*
//CTL1CNTL DD *
  SORT FIELDS=(1,10,CH,A)
  OUTFIL FNAMES=T1,REMOVECC,NODETAIL,
    SECTIONS=(1,10,
    TRAILER3=(1,10,X,COUNT=(M11,LENGTH=9)))
/*
//CTL2CNTL DD *
  OMIT COND=(12,9,ZD,EQ,+0)
/*
