You shouldn't be dimming an array twice without undimming it. The problem, in my opinion is that it let you do it twice without slapping your wrists.

But doing that would mean there would be problems with re-sizing the array inside a function. Phh, I may as well switch to using EMPTY ARRAY followed by ARRAY INSERT AT BOTTOM.

It's OK to dim an array a second time. It was Lees way of allowing us to resize a multidimensional array.

It also explains a problem I've noticed in a piece of code I wrote and didn't manage to track down at the time - I thought it was something I was doing.
