jargon /eks'ch*/ or /eksch/ To exchange two things, each for
the other; to swap places. If you point to two people sitting
down and say "Exch!", you are asking them to trade places.
EXCH, meaning EXCHange, was originally the name of a
PDP-10instruction that exchanged the contents of a
register and a
memory location.
Many newer hackers are probably thinking instead of the
PostScript exchange operator (which is usually written in
lowercase).
