You are most likely to seek help when you have a problem. For example, when you misspell a command or try to run a query that is not worded properly, QMF presents a brief explanation of the error on the message line of the panel. If you find you need more information about the error, you can ask for additional help by pressing the Help function key or by entering the HELP command on the command line. A panel displays with a detailed explanation of the error and a suggested way to correct the error.
For example, if you type the command SHOW PRFILE all in uppercase characters on the command line of the Home panel, you see the error message:
You cannot show PRFILE.
To find out more, press the Help function key.
Figure 5. QMF displays an error message when it can not execute a command.
+--------------------------------------------------------------------------------+ | +-----------------------------------------------------------------------------+| | | Help: Message || | | 1 to 8 of 22 You cannot show PRFILE. || | | || | | Explanation: || | | You can show only the panels with these names: || | | || | | Home Globals Form.Options Form.Break3 || | | Query CHARt Form.Final Form.Break4 || | | FOrm Form.Main Form.Detail Form.Break5 || | +-----------------------------------------------------------------------------+| | | F1=Help F3=Exit F4=More Help F6=Switch F7=Backward F8=Forward F9=Keys || | | F12=Cancel || | +-----------------------------------------------------------------------------+| +--------------------------------------------------------------------------------+
To scroll through the help panel, press the Forward function key. The help explains that the correct command is SHOW PROFILE.
If you want more related information, press the More Help function key. What you see depends on what you were doing before you first called for help. For example, if you were editing a table (in the Table Editor), pressing the More Help function key from the error message help panel displays the help panels associated with different aspects of the Table Editor. This is the same help that displays if you press the Help function key directly from the Table Editor. This list displays directly on top of the previous panel, the error message help panel, or any panel that is displayed from the Table Editor list.
You may also be presented with error messages as a result of a query being cancelled by the QMF Governor or the QMF High Performance Option Governor. For more information about the QMF High Performance Option Governor, see Appendix D, The QMF High Performance Option.
