#REDIRECT [[SELECT CASE#allCASES]]
|
|
|
|
[[CASE ELSE]] is used in a [[SELECT CASE]] procedure as an alternative if no other [[CASE]] statements are true.
|
|
|
|
|
|
{{PageDescription}}
|
|
* [[CASE ELSE]] should be listed at the bottom of the case list as it will supersede any case statements after it.
|
|
* Use it as a "safety net" or as an alternative for all values not covered in the [[CASE]] statements.
