No, Rohit.
Even accepting the 4.4 comparison for C'COUNT' as a typo, you don't want to use HEADER and COUNT, for your tests, as there is absolutely nothing to stop these giving you a "false hit" if they happen to occur in at that position in a name.
There are clearly indicators for the header and trailer which give no possibility of a false hit. There is also, clearly, a "reference number" which should be used for the sort/deduplication, even if that is not sufficient (no indication) there is no reason to includ the "05" or the blank following it or only a selected part of the name field.
WHEN=GROUP with BEGIN for "01", END for "99". Sort field after the ID to contain X'00' for header, X'FF' for trailer.
To suggest using COUNT, you can't chop off the extension in OUTREC.
A sequence, with RESTART for the ID extension and an IFTHEN=(WHEN=(logcicalespression) on OUTREC would allow a JFY with SHIFT=LEFT for the format of count shown.
