I agree with this advice completely.  It's too easy to forget to call
Skip_Line when there's a problem with the input, resulting in an infinite
loop.

As Jeff suggested, use Get_Line to read in the raw text, and then get the
enum value by using the version of Get that reads from a string.

This technique also allows you to pass meta-values as input, such as "first"
or "last" or "exit", etc.
