Before You Begin
Before you begin using HP C Online Help, you should review the following environment
variables.
You must set the DISPLAY environment variable to a (graphical mode) value that can
accommodate the display of an HTML browser. You may set the BROWSER environment
variable to point to the location of your HTML browser. If you do not set the BROWSER
