Copy CodeLIST OBJECTS LIKE A*
- TO PRINTER [PROMPT]
- Directs output from LIST OBJECTS to a printer. You can include the optional PROMPT clause to display a Print dialog box before printing starts. Place the PROMPT keyword immediately after TO PRINTER.

- ADDITIVE
- Appends to the end of the named file. If you omit ADDITIVE, then the file is overwritten with the value of the expression.
- NOCONSOLE
- Suppresses output to the main Visual FoxPro window or to the active user-defined window.

-
Properties and their values.

Member objects and the class or subclass on which they are based.
-
Class or subclass on which objects are based.
