I just got a compiler out of memory error when creating a dynamic array.
I'm on a steep and slippery learning curve but I suspect the problem is
here:- 
DIM DYNAMIC gGroupnote$(1000)
DIM DYNAMIC gGroupData$(1000,100000)
DIM DYNAMIC gGroupDataCount&(1000)

I didn't see that string or 2D DYNAMIC arrays were illegal.
Thanks
