In a traditional Pascal sense you could use a variant record:

false: (test : array[1..60] of byte);
end;

Daniel gave one reason that won't work -- .Net doesn't work that way. Another reason that won't work is that the two parts of the variant record aren't the same size. Char is a 16-bit type in .Net.

If you must have one-byte characters, use AnsiChar. If you must have two-byte characters, use WideChar. If you _don't care_ what size your characters are, use Char.
