Can anyone suggest a simple tool -- z/OS, USS, or Windows -- that would 
reformat the records breaking on every occurrence of a particular byte value? 

Is it a text file, or binary?

If it contains only printable display characters, you could FTP it to windows, 
and they use an editor to prepend the record prefix with CRLF.  Then FTP it 
back to z/OS.

If binary, I would just write a one-off ASM program to recover the original 
records.  It's probably a 30 minute task, easier than trying to learn anything 
new.
