[mapserver-users] Add points to shape

[Lowell Filak]

I don't believe mapscript is intended to edit the associated dbf files.
For instance if you look at the DBFInfo object you will see that it ONLY reads information rather than writes information.
At first this may seem strange but actually it makes sense for mapscript to not reinvent the wheel when there are other modules available for editting dbf files.
You will need to "use XBase;" in order to add records to the dbf file for the points you add.
