/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). [Jargon File] (1999-09-17)
