place a point in the map

[N M]

Hi David,

I follow all steps in the information on the URL you send me, I think that 
DSN runs perfectly, I created the TXT database, the OVF file and I modifed 
my .map file with the parameters of the example. My question now is, how can 
I calculate the EXTENT coordinates. When I had a shapefile I used it to do 
it. Which could be my .map file so I could display it?

Have I to change anything in my .map file so it runs? My EXTEND is the one 
of my old shapefile. Thank you
