Any idea how to check if a map (identified by its name) is already open ?
 
In my MapBasic code I run the same "Map From" line several times. This results 
in several instances of the same window. I'd like to put it in an "if ... 
then", but I have no idea how to check if the map is already open.
 
The complex structure of the program does not allow me to use a variable that 
holds info on the status of this map ("already open" or "not yet open").
