I am reading in a file that has a header of 11 lines
Code:
*---------
*
*
* HEADER TEXT
*
* MORE HEADER TEXT
* RANDOM STUFF
* MORE
* INFO HERE
* ++!!
*---+----1 END OF HEADER
If the header contains more than 11 lines the file has to be read in and the rest of the program has to process/complete but if there are only 11 lines (just the default header) no further processing has to be completed and the job has to end normally.
Code:
*---------START OF HEADER
* NONE OF THIS
* GETS PROCESSED
*
*
* MORE HEADER TEXT
* RANDOM STUFF
* MORE
* INFO HERE
* ++!!
*---+----1 END OF HEADER
THIS LINE WOULD GET PROCESSED
SO WOULD THIS LINE

How do you identify the beginning and ending of the header? Also what is the LRECL and RECFM of the dataset?

DeX,
Try this job. This job sets a return code of 0 when there are more than 11 as header and a return code of 4 when there are less than or equal to 11 header lines. You can check the return code and bypass/process the next steps
is the first include= a typo or should it be there?
It is a typo. I corrected it. You just need 1 include parm.

also what are the main differences between the statements?
Syncsort treats a SORTOUT DD connected to an OUTFIL statement as a SORTOUT data set, so NULLOUT applies to it. FNAMES=SORTOUT is treated differently than FNAMES=OUT1.
DFSORT treats a SORTOUT DD connected to an OUTFIL statement as an OUTFIL data set, so NULLOFL applies to it rather than NULLOUT. FNAMES=SORTOUT is treated the same as FNAMES=OUT1 which we feel is the more consistent approach.

I'm trying the DFSORT solution but no matter how many lines the input file is, it still finishes with a RC 0
You must be doing something wrong. Remember that we're only including lines with * in cc1. Could you be using Syncsort (WER messages) rather than DFSORT (ICE messages)? When I run this z/OS DFSORT V1R5 job:
Code:

//SORTIN DD *

* ++!!
*---+----1 END OF HEADER
//SORTOUT DD SYSOUT=*
//SYSIN DD *
SORT FIELDS=COPY
OUTREC FIELDS=(1,1,SEQNUM,8,ZD)
OUTFIL NULLOFL=RC4,INCLUDE=(1,1,CH,EQ,C'*',AND,2,8,ZD,GT,11)
/*
