FALSE

 Function
  To provide a named constant for the boolean false value in boolean
  expressions.

 Value
  0 = 0b = 0o = 0h

 Remarks
  BOOLEAN logic is based on two values: TRUE (1) and FALSE (0).  The
  literal numeric constants 0 and 1 may be used in expressions, or
  you may use the predefined named constants TRUE and FALSE.  They
  make for more readable, maintainable code and have no more overhead
  than any other constant value at run time.

 Example

  BOOLEAN flag
  LET flag = TRUE
  WHILE (!flag) DO
   INPUTSTR "Text",s,@X0E,60,"ABCDEFGHIJKLMNOPQRSTUVWXYZ",UPCASE
   PRINTLN s
   IF (s = "QUIT") LET flag = FALSE
  ENDWHILE
