SPUG: Stupid Ascii question

[Peter Darley]

Dan,
	I'd like to make sure that it can handle any normal (readable) text, since
I don't know what might be stored in the future.
Thanks,
Peter Darley

I have often used a separator like :::: (four colons), since the chances
of that occuring in the data fields I wanted to parse was slim to none.
That way you wouldn't have to worry about using non-printable chars.  It
does take up more bytes than a single char though.
