Yeah that can be especially annoying when you run programs from MirageOS since it doesn't zero out the getKey, so the very first getKey call in a MirageOS basic pgoram is always [2ND] or ENTER.  This can be exploited though to detect whether or not your Basic game is being run is Mirage ;)

I tried to do this and it didn't work, is there something wrong with it?
Code: [Select]
getkey->K
X+(K=2)-(K=3)->X

It works perfectly in 0.0.4 when I try that code.

Not sure if this might be the problem, but do realize that this:
X+(K=2)-(K=3)->X
Is not the same as this:
X+(K=2)-(K=3->X

The later will parse like this:
X+(K=2)-(K=3->X)
since store can be used inline.

Hmmm it seems that Axe computes 16*16*16 as Zero :(

EDIT: It seems the multiplication system in itself breaks under certain conditions, try running this program:

Code: [Select]
0->F
While getKey!=15
Output(0,0,2*F
Output(0,1,F+F
F+2->F
Pause 100
End
Unfortunately those two expressions are not equal for all legal values of F :(

Its not above the maximum value right?  Maximum for real numbers is 2^16 665536 if i remember correctly...
Yeah, that should come out to 4096 (which is less than 65536).
By the way, Quigibo, do you (or are you planning to) simplify expressions that use constants like that?

Hmm, addressing the screen shifting problem with output(), are you using a bcall? If you are, I think _putMAP fixes the screenshifting problem.

My bad!  The multiplication algorithm was incorrect, I had to change a z flag to an nz flag.  Sorry!  Until I update with the fix, you will not be able to multiply if either argument is larger than 255.

I am planning on optimizing the multiplication/division/modulo for constants as well as for equalities, bit operations, and other things.  I was still a little busy today though so I just wanted to get the update released on time so I'll do that later.

_putMAP would work, but that's how Text( will operate, so there wouldn't be a purose to having two commands that do the same thing.

Yay!

Ah..well...no text will be _VPutMap right?

Oh I'm sorry, I forgot about the differences.  I meant _VPutMap will be for Text().

I think there is a flag I can set to not auto-scroll the screen for the Output() command.  I'll have to do more testing.

In TI-BASIC, Output( command woN't scroll the screen, even if the string is longer than 128 characters. Only Disp does, when you display something on the 8th row.

TextScrolled(2) TextFlags(5)  - Text display caused screen to scroll

Would this be the right flag?

yeah, well _PutMap will do the homescreen, and it will not scroll.

The problem with this is that you can only output one character that way.
