The operator can request help within menu(C-1) by pressing the HELP key or the key sequence <F1> H. The default helpfile is:
\cbase\lib\cbase\help\menu if menu is displaying a menu.
\cbase\lib\cbase\help\param if menu is displaying a parameter form.
If there is a file with the same pathname as the menufile with a .h appended, this helpfile is accessed for searching and displaying help information whenever possible.
With menu, on-line help can be requested when selecting choices from a menu or when entering data into a parameter form that has been displayed for data entry. The sequence of calls and parameters passed to showtext, by menu, are different when help is requested from a parameter form or when selecting choices from a menu.
If a customized helpfile exists for a menufile, this menufile's helpfile contains the help sections for both menus and parameter forms. Under certain conditions, help sections are displayed from the default helpfiles for menus and parameter forms.
