Ok, I know this is small to start, but I had a question for something, can't seem to figure out a good way.

I was wondering how I could store the width and height to a variable so that I can have it edit the matrix column by column and not go over the defined width and height. Any Ideas or suggestions?

Did you have something like this in mind? Please also note where I changed your dim statement to be correct (it's {rows,columns}, not {columns, rows}).


Code:

Ok, could you explain how to use the DCS, I read about it, but it didn't make too much sense. Is it 3 variables, or a command used to add in DCS7?

You mean the DCS header? There's various types of Doors CS headers for BASIC programs, but they all provide one or more of three major features:

1) A custom icon
2) A custom description (that you can see via InfoPop)
3) Automatic unarchiving/archiving of subprograms

What I added is just a custom icon, feature (1) above. It's a capital M for Matrix, as in Matrix Generator. If you read through the first link below, it will tell you about the headers. The second link below will show you how to turn an 8x8 icon into that odd string of hexadecimal:

X=12345
Error # 518
Basic Ex ERR:DIM

When I hit goto, it takes me to this line:
X->[A](D,C

If anymore information is needed let me know.

You can't store to a matrix at 0,0
the first location is 1,1.
ERR:DIM is a dimension error just so you know

Yeah, that means you mis-copied my code, and used For(C,0,... and For(D,0,... instead of For(C,1,... and For(D,1,...

I know DIM is a dimension error, and I just copied the post KermM made, but if it was the location that caused the error, wouldn't it be a DOM error?

Domain errors are for things like trying to output at 0,0 or 9,17. Or trying to access a part of a string that you can't (0 or length(str)+1)

Indeed. Sonlen, did you double-check that you copied my code correctly, as per my post a few minutes ago?

How about on the graphscreen beyond the set window size?

Indeed, something like Pxl-On(99,99 would cause a DOMAIN error. Of course, Pt-*( commands would not do so.

Not trying to be mean, but I don't think it really matters what gives what errors, I personally think dim/dom interchangably. If I get one, I know I'm trying to go out of bounds of something.

KermM, you really need to test this, I can't quite figure out how to explain what it does >.<

Nevermind, I figured it out >.<

It prompts for the dimensions, then iterates over all the columns. For all the rows in that column, it prompts for a value for that (row, column) cell, then stores it.
