Do you maen that the DO CASE isn't running or the particular CASE branch doesn't seem to be taken? If it's the latter, you might want to try running the following commands and see what happens:

cS1 = "test"
cS2 = "test 1"
SET EXACT ON
? cS1 = cS2
? cS2 = cS1
? cS1 == cS2
? cS2 == cS1
SET EXACT OFF
? cS1 = cS2
? cS2 = cS1
? cS1 == cS2
? cS2 == cS1

Things to note:
* SET EXACT OFF is the default configuration
* Difference in behavior between "=" and "==" operator.
