I'm trying to get a program to do Gauss-Jordan reduction.
1. How do I find the number at a certain location in a matrix?
2. How are row operation commands used?
3. How do you determine the dimensions of a matrix?

To get the value of a matrix cell, do this:

Mat <letter>[x,y]

For instance, if I were to try to get the value of the cell 1,2 of Mat A, I would do this:
Mat A[1,2]

You can use that in an if statement as well:
If Mat A[1,2]=3
Then "Its 3!"
IfEnd
