Wow, you guys are awesome! So much has been written in just one night I came up with an approach similar to runner but instead I used 4 nested for loops

I'm making a program to find the matrix of minors ([wikipedia]http://en.wikipedia.org/wiki/Minor_(linear_algebra[/wikipedia])), and I keep getting a DIM error at [A](I,J)->(M,N). This is my code:

Prompt [A]
dim([A])ListDIM
ListDIM(1)->O
{O-1,O-1}->dim([B])
ListDIM->dim([C])

For(Y,1,O)
For(X,1,O)

1üM
1üN
For(I,1,O)
If I "is not equal to" R
1->N
For(J,1,O)
If J "is not equal to" C
[b][A](I,J)->[B](M,N)[/b]
N+1->N
End
End
M+1->M
End
End

det([B])->[C](X,Y)
End
End

Disp [C]

I don't see why I would get this error. Also, I'm basing this code on http://chi3x10.wordpress.com/2008/05/28/calculate-matrix-inversion-in-c/ inside this code block:
for(int j=0;j<order;j++)
    {
        for(int i=0;i<order;i++)
        {
            // get the co-factor (matrix) of A(j,i)
            GetMinor(A,minor,j,i,order);
            Y[i][j] = det*CalcDeterminant(minor,order-1);
            //Not including these 2 lines in the TI-BASIC version
            if( (i+j)%2 == 1)
                Y[i][j] = -Y[i][j];
        }
    }

I'm able to convert the midi file into a 8xp but when I choose to send to device, destination says "Incompatible Type".

That's fantastic! Thanks Squidgetx!

Umm, can I ask a question?

So, I'm trying to make a list of values, much of a Pascal triangle row. I'm expecting something similar to {1 5 10 10 5 1} like in TI-BASIC, or something that is workable with to get individual byte's value later on. I'm getting 34540 whenever I run the program.

EXC returns a factorial of a number. Each value in a pascal triangle row is found out by finding n!/(k!(n-k)!) where n is the nth row, in this case 5. k is from 1 to 5. First value in that row is 5, not 1. Because k cannot be 0, I declare L1 by starting with 1.

.PASCAL
ClrHome
sub(PAS,5)
Disp L1>Dec
Return

Lbl PAS
1->{L1}
1->C
For(J,1,r1
r1-J->B
sub(EXC,r1
A->C
sub(EXC,J
C/A->C
sub(EXC,B
C/A->C
C->{L1+J}
End
Return

Lbl EXC
1->A
For(I,1,r1
A*I->A
End
Return

EDIT: I just looked at Axe Q&A first page, and the first post says GDB cannot be modified. So I've modified the code above to see whether I can use free RAM, but I still get a number instead a range of numbers.

I found a way around using decimals numbers . thanks. I'm having a problem with calling sub functions. I'm using Ashbad's guide for Axe v0.5.3 because I've had problems of getting my RAM and Archive cleared when I used Axe v1.0.1. The problem I'm having with my program is that it display the value of C 6 times, even though I only ask for it thrice, and the value of C is even different from each other in every Disp call. the code is below:

.PAST

sub(PAS,5)

Lbl PAS
1->C
1->K
r1-K->B
sub(EXC,r1)
A->C
Disp C>Dec,i
sub(EXC,K)
C/A->C
Disp C>Dec,i
sub(EXC,B)
C/A->C
Disp C>Dec,i
Return

Lbl EXC
1->A
For(I,1,r1
A*I->A
End
Return

Display are as follow: 120, 120, 5, 24, 24, 4

EXC is used for factorials ! and PAS is to generate a binomial coefficient.

The value for C I expected is 5

I'm a bit confused about the number system. If a 1-byte number can have a range from 0 to 255, then why is it when I type 55 into notepad then look at it in a hex editor (HxD), I got 35 35? Isn't it supposed to be hold in one byte and not two bytes?

if I have an infinite loop in my application, is there a quit button like ON in Basic? and not having to take out the batteries?
