Second question: how would you make something move radially around a point (IE, the center of the screen) on the homescreen (not the graphscreen), so say in a "defend-the-castle" style game where you could have to shoot all the enemies coming your way, how would you rotate a character around whatever's in the center of the screen?

Sure.

I think there's a formula for determining what to do. I'll get back to you on that, but first, are the matrices square?
edit: oops, I was confusing this with 3D math. Never mind.

You would use sin( and cos( functions to do this inside something similar to a for( loop with the radius of the circle outside the two trig functions.
For example:
While 1
for(A,1,360
pt-On(10sin(A),10cos(A
pt-Off(10sin(A-1),10cos(A-1
End
End
Don't have enough experiance with matrices to answer the first question though sorry.

Besides, I need to an ASCII game. Every since I learned the wonders of xLIB, I haven't done anything in pure ASCII since... time to revisit...

[matrix1](a,c)->[flippeddimensionmatrix]((original left,right dimension) + 1 - c,a))
in actuality the code i had was:
dim([A] -> LSize
{LSize(2),Lsize(1)} -> dim ([J]
for a, 1, Lsize(1)
for c, 1, Lsize(2)
[A](a,c) -> [J]((Lsize(2) + 1 - c), A)
end
end
[J] -> [A]
delvar [J]

I'll try that, but instead of using a matrix, I'll make it use a Finance var so you can rotate really big selections without worrying about memory...

I was thinking that I could make it do that to rotate too, but I can't think of how I'd do that without having to draw it out on paper and look at it for a little while...
