Asm() does *not* actually have write back enabled, because when the program is run, it is copied to a separate location, but never copied back, so you need to force writeback yourself.  

MirageOS automatically performs writeback on all unarchived programs, and only does writeback on archived programs if you set the option yourself

DoorsCS uses "smart writeback," where it checks if the program data actually changed and writes back if it did.

Woops, my bad :P I just remembered that Space Dash had this issue where the sprites would change after the program quit or something because I was Exch'ing data within the program so I figured that Asm() did writeback or something (But maybe I was using MOS lol)

Code: [Select]
A?Pt-On(X,Y,Pic1)Is supposed to throw an error?  It seems like every time I try to do a Pt-blarg() it errors x.x

Yeah that should error.  That's like saying "A and Pt-On()" which doesn't make any sense since Pt-On() doesn't return a value.  In general, you can only use Axe commands that start with lowercase letters inline.  Uppercase commands have to start from a new line.

Ok, good to know.
Another one.  Is Buff()/Zeros()/det() in any of the menus?  I haven't been able to find it outside the catalog..

It's in the Matrix menu.

It would ignore the If statement if Q!=0, executing Stuff

Isn't that equivalent to If Q:If Blarg:Stuff:End:End? o.O

Theoretically, it could be abused, but it wouldn't be any more optimized than a regular if statement, just more cluttered and less readable.  I added the ? and ?? as operators specifically to avoid chains of if/while statements like If A:If B:If C:something:End:End:End should just be if A?B?C:something:End.  I don't want to allow intentionally misleading code as legal syntax when there is already a better way to represent it.

Huh.
Actually, Builder, that is not what it would do.
Q?If Blarg
stuff
Q?End
Would execute stuff if Q=0, or, failing that, if Blarg!=0
Key term here is "failing that". If Q=0, Blarg could be infinity (-1, anyone?) or it could be 0, and it wouldn't matter.
