Syntax
... ( ... case = case ... ) ...
Effect
Searches and comparisons in string functions are case-sensitive by default, but this can be overridden if necessary using the parameter case. The argument case requires a constant or a literal of the type ABAP_BOOL from the type group ABAP with the value of the constants ABAP_TRUE or ABAP_FALSE. If case contains the value of ABAP_TRUE, the search is case-sensitive; if it contains the value of ABAP_FALSE, the search is not case-sensitive.
