>Is it possible, from the main.prg, to map a drive letter to a path named "\\server\c\test" ?

UNC's are treated just like other paths so you can simply add it to your
SET PATH string like this:

  temp=SET("PATH")+"; \\server\croot\wconnect\wwdemo"
  set path to &temp

Of course you can also do stuff like:

USE \\server\croot\wconnect\wwdemo\tt_cust

directly. No need to map a drive...
