Description

If ConditionConditionConditionconditioncondition evaluates to 'true'"true""true""true""true" (not 0), the following block body up to the next corresponding block statement elseifelseifElseifElseifelseif, elseelseElseElseelse, or endifendifEndifEndifendif is executed. Reaching the end of the block the execution continues after the corresponding endifendifEndifEndifendif statement.

If ConditionConditionConditionconditioncondition evaluates to 'false'"false""false""false""false" (0), the execution is continued at the next corresponding block statement elseifelseifElseifElseifelseif, elseelseElseElseelse, or endifendifEndifEndifendif.
