>>>Explanation: If no destination is given in an SELECT - SQL command, a cursor is automatically created, and the result is shown in a BROWSE window. If the destination is anything else (for example, a cursor which you name explicitly), it won't be shown; to see the result, you have to explicitly give a BROWSE command, or some other command to show the data.
