REP

   <programming> A directive used in {IBM} {object code} {card
   decks} (and later {PTF Tapes}) to REPlace fragments of already
   assembled or compiled object code prior to {link edit}.
   Recompiling or reassembling the {source code} to produce a
   whole new object module was only possible if the {source code}
   was available, which it rarely was (if you had the object you
   were lucky!)  It was also quicker to apply incremental changes
   with REP cards and they also circumvented the {checksums} and
   {card sequence numbers} present in the object code.
