thank you mighty, now i know exactly how works linking.

For the optimizations, you save 5 or 6 bytes when doing this:
Code: [Select]
!If A-20
code...
End

instead of this:
Code: [Select]
If A=20
code...
End

Woah! I could never remember such thing, nice, it does make sense because if A is 20, A-20 will be 0, so !If...

Actually, is it an optimization in size and speed?  That's actually really nice. Because if A is less than 20, then it will just wrap around too. Very nice!

Yep, it's a really useful optimization, but it doesn't always work with negative numbers IIRC. Most of the time they never go negative anyway, though :D !If is awesome because it's exactly the same size as If .

Hmmm doesn't work for negative numbers?  Would't any number besides 20 give a non-zero result, and therefore not trigger the If statement?

EDIT: wow this optimization is incredible, is there any way to auto-detect this?

Warning ! It works with only one test, you cannot do this for example
Code: [Select]
If A-20 and (B-20)
code...
End

It does actually, you just have to be careful and use De Morgan's laws:

Code: [Select]
:If A=1 and (B=2)

To this:

:!If A-1 [16bit or] (B-2)

What saves more, this opt or the inData() trick? (assuming that the inData() routine already exists...and that there is only 1 comparison...iirc inData() with 1 comparison is like 12 or 13 bytes)

Also, nice game Fast Crash ;)

Thank you ! Now i have to finish linked multiplayer. It will be a bit slower than on-calc multiplayer, but that'll be fun :) . I just need mighty moose to test the first playable version.

I think I made a post about this a while ago...

Ah yes, I did! Here it is. You have to remember that inData() only works with bytes though, not with words like normal equality checks.

thank you but i found how to link 2 calcs on wabbit emu.
I just have a question: does the linking command use variables? or pointers? currently only constants work perfectly.

Run wabbit emu.
File -> New
Calculator -> Connect to...

And it should work :)
