Peter,
gnererally speaking ABAP is not case sensitive but if you use literals or strings, they are.
So 'c' = 'C' is not true.
But there are exceptions when it comes to certain operations.

As for ddic-elements (and the variables referring to them) it is either the data element or the domain where you have to allow case sensitive.
But if you want to have case sensitve entries in your database table, keep in mind that a select might not give the desired results.
select name from database where name = 'MEYER' does not reveal an entry if on database leve the entry 'Meyer' is stored.
Abap statements, variable names or the name of ddic elements are not case sensitive.

is equal to ä
WRITE: MARA-MATNR.
But SET PF-STATUS 'TEST' is not equal to SET PF-STATUS 'test'.
