CASE IS can be used in a SELECT CASE routine where you need to use relational conditional expressions.


Syntax

CASE IS {=|<|>|<=|>=|<>|NOT} expression


Description

  • AND can be used to add extra conditions to a CASE IS statement evaluation.
  • OR can be used to add alternate conditions to a CASE IS statement evaluation.
  • Parenthesis are allowed in CASE IS statements to clarify an evaluation.
  • CASE IS > 100 uses the greater than expression.
  • CASE IS <= 100 uses the less than or equal to expression.
  • CASE IS <> 100 uses the not equal to expression(same as NOT 100).
