[[ELSEIF]] is used in an [[IF...THEN]] block statement to offer an alternative condition.


{{PageSyntax}}
: [[IF]] {{Parameter|condition}} [[THEN]]
:: ''{code}''
:: ⋮
: [[ELSEIF]] {{Parameter|condition2}} [[THEN]]
:: ''{code}''
:: ⋮
: [[ELSE]]
:: ''{alternative-code}''
:: ⋮
: [[END IF]]


{{PageDescription}}
* ELSEIF statements require a '''separate''' code block line with [[THEN]] for each alternative condition.
* There can be more than one [[ELSE]] IF statement in a single-line IF statement.
* If there is only one possible alternative condition (such as 0 or [[NOT]] 0), use [[ELSE]] instead.
* If the comparisons are based on multiple conditions being true, it may require many ELSEIF comparisons. ELSE could help cover some of those conditions.
* You can use [[SELECT CASE]] when IF blocks have a long list of alterative ELSEIF conditions.
