The IF and ENDIF statements are used in the Event Handler. If the expression following the IF evaluates to the number zero, the following statements are skipped until a (matching) ENDIF is found. The IF statement can test numeric values only.
The IF - ENDIF statements can be nested.
The statement STOP stops the execution of the action string.
Example:
Action commands:
IF %udd(1) LOG “Variable 1 is true” STOP ENDIF LOG “Variable 1 is false”
