This "text viewer/hyperlink program" was brought to you by William Yu.
No other person gives you more bugs or headaches, than with his programs.
Please use and distribute freely, because I know this doesn't work properly
and the whole world is just waiting to e-mail me about it!

' The not so BASIC text viewer... with hyperlinks (sort of).
' This text viewer runs as is, or with special markers (like in HTML)
' Only problem is, this viewer doesn't work properly, go figure ;-)
' Anyway, I haven't done anything with this thing in 3 years, so if
' you want to expand on it, by all means, it's public domain, do
' whatever you want with it.
