Right off the bat I will say this has absolutely nothing to do with Microsoft Visual Basic.
Recently I've been practicing language design and development and I've written a few basic interpreters for calculator languages and such and I've decided for some more practice I want to write a basic BASIC interpter (haha, basic basic...). After searching around I've decided this is a fairly common practice (as far as language design goes) but there's one thing I don't understand. Obviously from the original there have been TONS of BASIC dialects, I don't know which to try to implement. Is there an existing ISO or ANSI standard for example? I want a dialect as original and modern as possible, does anyone know of any documentation that exists anywhere I can read through and use to implement this? Thanks for any suggestions.
