The OR conditional operator evaluates an expression to true (-1) if any of the arguments is also true.



IF expression1 OR expression2 THEN {code}


  • OR adds an alternative to another conditional evaluation. If either element in the evaluation is true then the evaluation is true.
  • Parenthesis may be used to clarify the order of comparisons in an evaluation.
  • Not to be confused with the AND and OR numerical operations.

Relational Operators:
Symbol Condition Example Usage
<  Less than  IF a < b THEN
>  Greater than  IF a > b THEN
=  Equal  IF a = b THEN
<=  Less than or equal  IF a <= b THEN
>=  Greater than or equal  IF a >= b THEN
<>  NOT equal  IF a <> b THEN



a% = 100 b% = 50 IF (a% > b% AND a% < 100) OR b% = 50 THEN PRINT "True"


Explanation: The first evaluation was False, but the OR evaluation made the statement true and the code was executed.
