No (I would have suggested it if so; it's much easier). You can't use a
string variable as a case selector, it needs to be an ordinal expression.
Single characters are OK (the char type is an ordinal type), but strings
are not - the best you can do is "if... else if... else if... " chains
for those.

In this case you are only interested in one character, so I suggested the
case construction I gave previously. I think it's probably the nicest way
in this sort of situation; but "if... else if..." is reasonable too.

Not really, I just have a bit of experience.
