In my prgm, one function has an array passed in as a parameter. Is there anyway to find out the dimensions of the array without having extra variables? Such as ArrayWidth(m:Int[]) or ArrayHeight(m:Int[]). Is this possible?

len(myArray[])

or I believe you can do:

myArray.Length

*EDIT*
if you are using the arrays within arrays trick then you can get both width and height with this.

Maybe a silly question but I'm new here :) No multidimensional arrays? Ok, so I know I can use a one dimensional array and some simple arithmetic, or even a list. Sometimes, though, you just can't beat map[x][y] :)

Am I missing something?

There are multi-dimensional arrays.
From the Wiki...
