How a Help Volume Is Found

The Help System uses desktop search paths to locate help volumes. When help is requested within an application or a help volume is specified in a command line, the help volume is found by checking a set of search path directories. You can control the directory search path for help volumes by modifying several environment variables. Refer to the CDE Advanced User's and System Administrator's Guide for detailed information about specifying search paths.
