Speaking of which, I have a vague recollection of "Tiny BASIC". Never did
actually use it, though. Any of you guys familiar with it? Is it all that
usable? At all extensible? I can see where it might be handy for some
stuff...
Hi
A search on the web will show a couple of listing of a version of Palo
Alto Tiny BASIC that I posted years ago. It was slighly modified from the
original to allow on to expand it. It had I/O for the Poly88 but it could
be easily connected to any serial streams terminal.
It fit in 2 2708s which was great for the Poly88. I wrote 3 extentions that I used. These could be
loaded on the fly from the
cassette tape, with the BASIC program that that used them. I added PEEK,
POKE and SAVE. PEEK and POKE were useful with the Poly88's video. SAVE made
it simple to save any new programs that also need these extras. The bad part
was that the extended code had to be done in assembly code and required a
reasonable understanding of how Tiny BASIC worked inside.
I guess that could be expected.
If one wanted to work with an extensible language,
Forth is the most
flexible. It is also one of the best for understanding more complex
programming concepts. It isn't that it has them built in, it is that it
contains all the building blocks needed to create them.
Forth is definitely one of the other things that I'm looking at, but it's
style is rather putting me off. I have a 68HC11-based board that comes up in
it, and should probably hook it up and play with it one of these days, or
get an emulator going, or something, just to try and get a handle on it.
If you know of any online resources for that language I'd sure like to hear
about them. I did snag two of Leo Brodie's books, for starters, but not a
whole lot else.
