The ''WAIT'' command is used to halt the program until the contents of a memory location changes in a specific way.

===== Syntax =====

  WAIT <address>, <mask> [, <trig>]

The contents of the memory location are first exciusive-ORed with <trig> (if present), and then logically ANDed with <mask>. If the result is zero, the program goes back to that memory location and checks again. When the result is nonzero, the program continues with the next statement.
