Well this isn't a language issue but i thought it may be interesting.
I have seen some examples of networking with DBPRO, and they all do something like this to select the TCP/IP connection
if checklist string$(a)="Internet TCP/IP Connection For DirectPlay" then netsel=a
That works only if the user operating system is in english, so it wasn't working for me, as i'm from Argentina and i have it in Spanish.
Just thought that was nice to share

Here's a quick "fix"
if find sub string$(checklist string$(a), "TCP") then netsel=a
