Well that make for much cleaner code, thanks. I remember you could do something like that in QBASIC but not in Ti-Basic.

So are the following equivalent?

Thanks for the link. I am confused, though, I am used to the following syntax: if ans != 0 and ans !=21 then ans -> k end If : is just the same as a new line, then what how come the following doesn't need a then, an end, or a logic operator for the first comparison? if ans and ans != 21:ans -> k

Well, now it won't accept 2nd as input.

Does the ":" equate to a "then"?

Awesome, that works and keeps the speed fast even when a key is held. However, I had no idea something like this could be done and still barely understand : does. Where can I read up on this sort of stuff? I also wanted a variable F that switches between -1 and 1 when 2nd is pressed, an I came up wi...

Huh, I didn't know you could do that. How would you get it to continue in the direction of the keypress without needing to be held down?

I don't know if something like this has been posted, but I used this in my Tron Basic program and it sped up quite a lot: instead of getkey -> g if g = 24 then ... end if g = 25 then ... end I did this getkey -> g if g != 0 if g = 24 then ... end if g = 25 then ... end end The only problem is that t...

That makes sense. Took me a while to wrap my head around, but I understand how that's superior to Ti-Basic. It reminds me of assembly, actually (though less difficult). One thing I learned in QBASIC that I miss in Ti is the one-line if statement like you have in your example. That reminds me of anot...

No no, if it wasn't for you I wouldn't even have thought of the idea! This has gotten me really interested in computer hardware rather than just the software end. But what do you think of running z80s in parallel? If one assembled it as a multi-core processor there would probably have to be some sor...

Wow, that looks great.

Does BBC Basic use loops or gotos more? If the former, I'd definitely use it over Ti-basic. If the latter, I still might check it out. Having 0,0 in the lower left corner is almost reason enough to use it.

Yeah, the idea (to get SymbOS running) has kinda been losing steam. Thanks a ton for all your comments, I certainly hope to get SOMETHING up and running, if only a text-based something. Out of plain curiosity, what would you think of getting multiple z80s to run in parallel? I imagine one could get ...

Is it possible to replace Ti-OS with something else? Not that'd it'd be particularly useful, but it'd certainly be interesting. My guess is that it's stored in ROM somewhere, which could be difficult to access. On the other hand, Ti does update the OS, so it's may be possible. Any thoughts?

What sort of chips can be used as video chips?

You may have to source a clone of the video chip used in the MSX2/CPC/whatever hardware SymbOS targets if you can't write your own video driver. Hmm... but I wonder how that would interface with the LCD? This seems like it's getting harder every minute. Maybe I'll try and just get a linux shell run...

Wouldn't that interfere with SymbOS / whatever I manage to get on there?

So will this driver be inherent in the wiring? Or will it be software?
