NAME
  WAIT Statement

SYNOPSIS
  WAIT portnumber%, AND-expression% [,XOR-expression%]
      o portnumber%        The number of the input port.
      o AND-expression%    An integer expression that WAIT combines with the
                           bit pattern value using an AND operator. When the
                           result is nonzero, WAIT stops monitoring the port.
      o XOR-expression%    Can be used to turn line bits on and off in the bit
                           pattern before the AND operation is applied.

DESCRIPTION
  Suspends program execution until a specified bit pattern is input from an
  input port.

  Example:
      'Reads the interrupt controller port address &H20.
      'Press any key to continue.
      WAIT &H20, 1
