TRUE

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

 Value
  1 = 1b = 1o = 1h

 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
