     <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-10
     instruction 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).
