The OR conditional operator evaluates an expression to true (-1) if any of the arguments is also true.
Contents
Syntax
- IF expression1 OR expression2 THEN {code}
Description
- 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.
| 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 |
Examples
Example:
a% = 100 b% = 50 IF (a% > b% AND a% < 100) OR b% = 50 THEN PRINT "True"
True
- Explanation: The first evaluation was False, but the OR evaluation made the statement true and the code was executed.
