1 - Create the ODBC connection.
 2 - Use SqlConnect function to connect ODBC. Eg.: 
     lnCon = SqlConnect("TesteDBF", "", "").
 3 - Use SqlConnect function to Select, Insert, Delete data from table. Eg.:
     SqlExec(lnCon, "Select * From MyTable")
     SqlExec(lnCon, "Insert Into MyTable (Field1, Field2) Values (Val1, Val2)")
     SqlExec(lnCon, "Delete From MyTable Where Field1 = 1")
 4 - Use SqlDisConnect function to disconnect ODBC. Eg.:
     SqlDisconnect(lnCon)
