I know your trying to stay away from MapScript but I would suspect with
it you could do a queryByRect (current extents) on the points layer and
then loop through the resultCacheObj for each resultCacheMemberObj
grabbing the shapeindex for the current point and create a pointObj for
that shapeindex in the layer and then use the pointObj draw method
specifying the 'character text' value as the sequential number.
Clear as mud...
