SHOWHELP( )

The SHOWHELP( ) function displays a Help message, corresponding to its specified SMALLINT argument, from the current Help file.

The argument of SHOWHELP( ) identifies the number (between 1 and 32,767) of a message in the Help file that was specified in the OPTIONS statement.

When it is called, SHOWHELP( ) opens the Help window, and displays the first (or only) page of the Help message text below a ring menu of Help options. This menu is called the Help menu.

If the Help message is too long to fit on one page, the Screen or Next option of the Help menu can display the next page of the message. The Previous option re displays the previous page. The Resume option closes the Help window, and returns focus to the Application window.

In interactive statements like CONSTRUCT, INPUT, INPUT ARRAY, PROMPT, or the COMMAND clause of a MENU statement, the effect of SHOWHELP( ) resembles that of the Help key. The Help key, however, displays only the message specified in the current HELP clause.
