3.2.1 Environment

The system is currently implemented to run under the X Window System, Version 11, and you must be using a console or monitor running X11 or a compatible windowing system.

FDR insists on one variable being set in its environment: FDRHOME must be set to the (fully qualified) name of the directory containing the FDR `LICENCE' file, typically the root directory of the FDR installation. If this variable is not set, the tool will terminate immediately with an error.

A number of other environment variables may be set, to select variant screen layouts and preferred editors, for example. In most cases the default values will be appropriate.
