Peter,
It is quite simple to verify the variable length. You just need to use UFF
( Unsigned free format ) instead of ZD which will automatically format the
variable value by ignoring any thing other than a numeric and pad it with
zeros.
Example :
//SYSIN DD *
OPTION COPY
INREC IFTHEN=(WHEN=INIT,
BUILD=(1,4, $ RDW
SEQNUM,11,ZD, $ RECORD NUMBER
005,15)), $ INDICATOR+COUNT
IFTHEN=(WHEN=(16,4,CH,EQ,C'0999'), $ IF TRL RECORD
OVERLAY=(5:5,11,ZD,SUB,+2,M11,LENGTH=11)) $ SUBTRACT 2
OUTFIL FNAMES=SORTOUT,NULLOFL=RC4,
INCLUDE=(16,4,CH,EQ,X'0999',AND, $ TRL RECORD
(05,11,UFF,EQ,20,11,UFF)) $ IS COUNT=TRL COUNT?

Thanks again Sri, your new version also worked as long as I changed the
OUTFIL DD name.
Another colleague came to me with this one today. How could we handle
variable-length count data in a trailer? For example (RECFM=VB file):
0000,This is a header
0100,data record 1
0100,data record 2
Etc.
0100,data record 21
0999,21
The last record is a trailer with variable-length data record count.
Maximum count field length is 11.
TIA for any suggestions you can offer.
Peter

Peter,
Your control cards looks good. I cannot comment on syncsort's NULLOFL
behavior. I think Alan had already pointed the obvious. So you control
cards should work as expected with that minor tweak.
I believe you just need to set the return code if the counts do NOT match
and there is no point in making another copy of the dataset. So why not
copy only the relevant portions that we need. Some thing like this
//SYSIN DD *
OPTION COPY
INREC IFTHEN=(WHEN=INIT,
BUILD=(1,4, $ RDW
005,01, $ INDICATOR
SEQNUM,11,ZD, $ RECORD NUMBER
145,11)), $ RECORD COUNT
IFTHEN=(WHEN=(5,1,CH,EQ,X'FF'), $ IF TRL RECORD
OVERLAY=(6:6,11,ZD,SUB,+2,M11,LENGTH=11)) $ SUBTRACT 2
OUTFIL FNAMES=SORTOUT,NULLOFL=RC4,
INCLUDE=(5,1,CH,EQ,X'FF',AND, $ TRL RECORD
(06,11,ZD,EQ,17,11,ZD)) $ IS COUNT=TRL COUNT?
//*
Further if you have any questions please let me know

Hi Sri,
I am a colleague of Victor's, and the initial problem was not stated quite
correctly. The input file is RECFM=VB, and the trailer record is
identified by X'FF' in the first data position. The record count to be
checked in the trailer record is at positions 145-155 (11 digits, ZD). The
count in the trailer record does not include either the header record
(X'00' in the first position) nor the trailer record, so the count in the
trailer record should be the actual record count minus 2. The desired
result is to check the trailer count versus the actual data record count
and set RC=4 if they do not agree.
Unfortunately we do not actually have access to DFSORT any more, only
Syncsort. May I ask you to please verify for me that if we were using
DFSORT that the control cards below would do what we wish? If so then I
can go to our Systems Programmers to open a ticket with Syncsort for
assistance in verifying the operation of NULLOFL=RC4 in their product.
When I use these control cards with Syncsort, the output file is null (has
no records) but Syncsort is not setting RC=4, so I will go to them for
support if the control cards I am using should give RC=4.
OPTION COPY
* ADD SEQNUM BETWEEN RDW AND DATA.
INREC IFTHEN=(WHEN=INIT,BUILD=(1,4,5:SEQNUM,11,ZD,16:5)),
* USE SEQNUM-2 TO PUT COUNT OF DATA RECORDS IN POS 20 OF
* LAST RECORD (IDENTIFIED BY X'FF').
IFTHEN=(WHEN=(16,1,BI,EQ,X'FF'),
OVERLAY=(020:5,11,ZD,SUB,+2,M11,LENGTH=11))
OUTFIL NULLOFL=RC4,
INCLUDE=(016,1,BI,EQ,X'FF',AND,
(160,11,ZD,EQ,20,11,ZD)),
BUILD=(1,4,5:5)
Thank you for your generous and expert assistance on this forum.
Peter

Victor Gil,
It is quite simple to verify the number of records and validate it against
the trailer record and if the record count match the return code is 0 and
if the count is off then the return code is set to 4.
I assumed that the trailer record is not counted as part of the record
count. If it is indeed counted then simply remove the ",START=0" on the
INREC statement.
Use the following JCL
//STEP0100 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTIN DD *
A
B
C
D
RECS=00005
//SORTOUT DD SYSOUT=*
//SYSIN DD *
OPTION COPY
INREC OVERLAY=(81:SEQNUM,5,ZD,START=0)
OUTFIL NULLOFL=RC4,
INCLUDE=(1,5,CH,EQ,C'RECS=',AND,
(06,5,ZD,EQ,81,5,ZD))
//*
The above job will end with RC=4 as there are only 4 records but the
trailer says 5 records.
Further if you have any questions please let me know
