Copy(FlipV(Pic1),Pic2,8)
Copy(RotC(Pic2),Pic3,8)

Of course, Pic2 and Pic3 have to be defined and 8 bytes large
When you do this, if your game has an appvar save file, you should have an "Initialized" variable in it or compare it with a version number to make sure the game only does this once (to prevent it from writing back and wearing down your archive).

For any and all drawing commands, command()rr to perform the command on both buffers. (L3 and L6)

A way to manipulate individual bits.

And Try/Catch

And Try/Catch

The OS doesn't throw enough errors for that to be useful, though.

And when it does error, it's usually a RAM clear. You can't really stop that, unless you're willing to operate your calc with corrupted system RAM.

is there also a way to use just B_CALL _getKey so that you can detect key combos (I mean, like with 2nd-> Math)

Code: [Select]
:If getkey(54) and (getkey(47)
stuff
:End

He meant pressing 2nd, then MATH, like you do in the OS. A way to do bcall(_getKey) is

Code: (Axe) [Select]
Asm(EF724926006F)
It involves a whole other key system though.
Yes, I know. I dont know how to read register A with Axe, though...

Just use that code I gave you. It loads A into HL so you can use it ;)

Persistent interrupts would be very cool.  Also, try/catch requires OS level support, which isn't there.  Wait for KnightOS.

Stateful ComeFrom and multitasking.

Multitasking would be difficult on a Z80... It can be done, but it would be slow and running two tasks would be slower than running each one separately :D

comeFrom might actually be possible, but we can't even access the current pointer right now.

So as a bump for a feature request: Getting PC (or at least the pointer to a label).

Multitasking is always slower than two tasks independently. You can't just make a processor suddenly divide into two or something.

And as a reminder, make sure feature requests are things you're actually going to use, not just things that sound cool ;)

I would use a stateful ComeFrom, actually. What the stateful means is that it's actually a conditional, so when the argument becomes true, control flow leaps to the ComeFrom from wherever it was in the program.

Yeah, the Z80 wasn't designed for multitasking and personally I am glad about that :D The closest you can come to that is using an interrupt. It might be cool to make an interrupt that interprets code like a BASIC language while executing assembly, but the thing is interrupts will slow down your regular code (though it isn't usually noticeable). For example, if your interrupt took 1/220th of a second to run, that would mean that your regular code ran at half of its max speed, I believe.

My spring break is next week.  I will finally have time to pick this project up again so expect an update in about a week.  I know there have been a lot of bugs/feature requests recently that I've probably forgot about or missed, I will try to reread most of the features wishlist, bug reports, and optimization threads on Friday so if there are any other important things you feel I should do not already mentioned in those threads, now would be a good time to bring them up there.
I'm glad to hear. Good luck :D
