Table-lookup?!?

It's a very simple technique: in general, you use an array indexed on
your input tokens, containing your output tokens.

For things like a scanner for a parser, you probably have to scan
through a list of your input tokens, but for a simple character encoding
conversion, you just construct an array containing the output encodings,
in order of their input encodings, e.g., an array of the EBCDIC
character encodings in ASCII order, or vice versa.

The RPG XLATE statement is another example of a simple table lookup.
