This function returns the dimensions of an array.
The dimensions are returned in a second array.
For Example:
Dim a(0)
Dim b$(3,5,9,10,11)
a() = GetDim(b$())
For i=0 to a(0)
Print i,a(i)
Next i
0 5
1 3
2 5
3 9
4 10
5 11
Notice a() is redimensioned to fit the number of dimensions of b$(). a(0) contains the number of dimensions. a(1) through a(n) contain the dimensions of b$().
