The '''OR''' coditional operator adds an alternative in a [[IF...THEN]] or [[Boolean]] statement.

{{PageSyntax}}

|
:: IF a = 1 '''OR''' a = 2 THEN a = 0
|
|
|
|
|
|
* OR adds an alternative to another conditional evaluation. IF True then the statement evaluation is True.
|
|
* Parenthesis may be used to clarify the order of comparisons in an evaluation.
|
|
* [[AND]] and '''OR''' cannot be used to combine command line operations.
|
|
* '''A double OR syntax error may be ignored and create a QB64 compiler error!'''
|
|
* Not to be confused with the [[AND]] and [[OR]] numerical operations.
