Filling in arrays with points data and retrieving/cycling through the data

[simurq]

Hello,

I'd like to construct variable-length polygon arrays, which contain a set of points given their coordinates. Each point has two coordinates (x, y). Eg.:

poly001 = [ (x1,y1); (x2,y2); ... (xn, yn) ]

where (x1,y1) ... represents the first point in 1-dimensional array.

I'm also thinking about using 2D arrays like this:

Dim poly001(6, 6) As Double, poly002(7, 7) As Double, poly003(5, 5) As Double, poly004(8, 8) As Double

Since the bounds of dimensions are equal (naturally), I'm also fine if the first dimension contains X values and the second dimension contains Y values.

But then I don't know how to retrieve and cycle through the data (points) in them.

So, the questions are:

i) which array type to use? 1D or 2D
ii) how can I fill in and retrieve data from these arrays?

Thanks!
