Here's a DFSORT/ICETOOL job that will do what you asked for:
| Code: |
//S1 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN DD DSN=... input file
//CTL2CNTL DD DSN=&&C1,UNIT=SYSDA,SPACE=(TRK,(1,1)),DISP=(,PASS)
//OUT DD DSN=... output file
//TOOLIN DD *
COPY FROM(IN) USING(CTL1)
COPY FROM(IN) TO(OUT) USING(CTL2)
/*
//CTL1CNTL DD *
OUTFIL FNAMES=CTL2CNTL,REMOVECC,NODETAIL,
BUILD=(80X),
TRAILER1=(' OPTION STOPAFT=',COUNT-1=(M11,LENGTH=8))
/*

| Code: |
TRAILER1=(' OPTION STOPAFT=',COUNT-1=(M11,LENGTH=8))
|
TRAILER1 builds a record with the count-1(total count of records - 1) at the last page of the report(however here we have mentioned NODETAIL, so TRAILER1 would be the only line on the o/p in this case). Finally TRAILER1 is building a control card CTL2CNTL.
To understand the working of TRAILER1 just try executing this
| Code: |
//****************************************
//STEP1 EXEC PGM=ICEMAN
//SYSOUT DD SYSOUT=*
//SORTIN DD *
ASDF
qwer
//SORTOUT DD SYSOUT=*
//SYSIN DD *
OPTION COPY
OUTFIL NODETAIL,REMOVECC,
TRAILER1=(' OPTION STOPAFT=',COUNT-1=(M11,LENGTH=8)) |
Also look at "Display the number of input or output records" here

It's not clear what you mean by this. What do you want to do exactly? Please be more specific.
If you're not familiar with DFSORT and DFSORT's ICETOOL, I'd suggest reading through "z/OS DFSORT: Getting Started". It's an excellent tutorial, with lots of examples, that will show you how to use DFSORT, DFSORT's ICETOOL and DFSORT Symbols. You can access it online, along with all of the other DFSORT books, from:
www.ibm.com/servers/storage/support/software/sort/mvs/srtmpub.html |

You can do this kind of thing quite easily using the new SUBSET operator of DFSORT's ICETOOL available with z/OS DFSORT V1R5 PTF UK90013 (July, 2008):
| Code: |
//S1 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN DD DSN=... input file
//OUT DD DISP=... output file
//TOOLIN DD *
SUBSET FROM(IN) TO(OUT) INPUT REMOVE LAST
/*
|
The above job removes the last input record. If you want to sort the records and remove the last sorted record, you can use a DFSORT/ICETOOL job like this:
| Code: |
//S2 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN DD DSN=... input file
//OUT DD DISP=... output file
//TOOLIN DD *
SUBSET FROM(IN) TO(OUT) OUTPUT REMOVE LAST USING(CTL1)
/*
//CTL1CNTL DD *
SORT FIELDS=(1,10,CH,A)
/*
|
For complete details on the new SUBSET function and the other new functions available with PTF UK90013, see:
