I'm not a TP expert, but Pascal (in general) does not allow nondiscrete types
in case statements.  STRING is definitely nondiscrete!  

A list of if-then's in not so bad if you structure them correctly.  After all
isn't that what case is all about?  As an alternative you may want to convert
the string or part thereof to an enumerated type and use a variable of that
type in the case statement; however, in general, this does not allow for
string's that don't conform to the type.
