From Jargon File (4.3.1, 29 Jun 2001) [jargon]:

  EXCH /eks'ch*/ or /eksch/ vt. 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).
