Maybe I don't understand what you're trying to do, but if you just want to
add the same header at the top of each file, just have the REXX generate an
OUTFIL HEADERx statement along with the OPTION and SORT statements:
OPTION NULLOUT=RC4
SORT FIELDS=COPY,STOPAFT=50000,SKIPREC=150000
OUTFIL REMOVECC,HEADER1=('THIS IS THE HEADER')
