Easy question.  How do you create a dynamic 2D array?  And then how do you redim this array (what is the syntax)?

If you wish to resize the array and preserve the contents, use Redim Preserve.  For arrays with more than one dimension, you can only resize the final dimension, so do your planning carefully.

'Create dynamic array
dim intNum() as Integer

'Now use redim to make 2 dimensional
Redim intNum(1 to 3, 1 to 10)

intNum(1,1) = 5

'Resize final dimension...
Redim Preserve intNum(1 to 3, 1 to 20)

SO how would you go about redimming the first dimension?

You can redim the whole thing if you don't need to preserve the contents.
