EXCH
/eksch@/ , /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).
