The following method retrieves all the data sources and their descriptions and puts them into two arrays:

 ARRAY TEXT(arServer;0)

 ARRAY TEXT(arDescription;0)

 $result:=ODBC_SQLDataSources(SQL_FETCH_FIRST;vServer;vDescription)

 If($result=SQL_SUCCESS) `If it's successful, there might be other data sources

    Repeat

       APPEND TO ARRAY(arServer;vServer) `add server name to end of the array

       APPEND TO ARRAY(arDescription;vDescription) `add description to end of the array

       $result:=ODBC_SQLDataSources(SQL_FETCH_NEXT;vServer;vDescription)

    Until($result=SQL_NO_DATA) `loop until no data is retrieved by the command

 End if
