Prism's Online Help Systems

There are several ways in which you can get help in Prism:

• The Help menu in the menu bar provides help on several major topics. It includes the Help Index, which gives in-depth information about all aspects of Prism. See " Choosing Selections From the Help Menu".

• The Help selection in menus and the Help button in windows and dialog boxes provide instructions for using these screen areas. Pressing the F1 key in a window or dialog box also displays a help screen.

• Command-line help provides information about commands you can issue from the command window.

Using the Browser-based Help System

Prism displays its help files via your World Wide Web browser. The default browser is Netscape(TM), although your system administrator can change this. To specify which browser you want to use for graphical Prism, set the Prism resource Prism.helpBrowser to the executable name of the browser; see " Specifying the Browser to Use for Displaying Help".

If you don't have a browser running, Prism starts one. If you have a browser currently running as you use Prism, by default Prism displays the help information in that browser. You can change this behavior via the Prism.helpUseExisting resource; once again, see " Specifying the Browser to Use for Displaying Help".

See " Setting Up Your Environment" for important information about setting up your environment for Prism's use of your default browser to display Prism's online help files.
