See [SELECT CASE](SELECT-CASE).
|

|
|
|
||
|
|
[CASE IS](CASE-IS) can be used in a [SELECT CASE](SELECT-CASE) routine where you need to use relational conditional expressions.
|
||
|
|
|
||
|
|
## Syntax
|
||
|
|
|
||
|
|
> [CASE IS](CASE-IS) **{=|<|>|<=|>=|<>|[NOT](NOT)} expression**
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
* [AND (boolean)](AND-(boolean)) can be used to add extra conditions to a [CASE IS](CASE-IS) statement evaluation.
|
||
|
|
* [OR (boolean)](OR-(boolean)) can be used to add alternate conditions to a [CASE IS](CASE-IS) statement evaluation.
|
||
|
|
* Parenthesis are allowed in [CASE IS](CASE-IS) statements to clarify an evaluation.
|
||
|
|
* [CASE IS](CASE-IS) > 100 uses the greater than expression.
|
||
|
|
* [CASE IS](CASE-IS) <= 100 uses the less than or equal to expression.
|
||
|
|
* [CASE IS](CASE-IS) <> 100 uses the not equal to expression(same as [NOT](NOT) 100).
