Preferences and Initialization File
Configuration settings which pertain to running the Enif program
as such (i.e. not related to the configuration of plots or lists)
are handled by a configurable object we refer to as the preferences.
The preferences consist of a set of parameters which are divided into
the following groups:
All system defined parameters are organized in a single parameter list.
Separate parameter lists are used to contain each of the following
types of user defined parameters:
predefined views, registered plot configurations, registered list
configurations and user defined styli. This allows each parameter type
to have its own name space, so that no conflict occurs if e.g. a
predefined view uses the same name as a registered list.
- General parameters containing information about the
default data bank, the default startup plot configuration or
the diagnostic log file.
- Layout parameters which define the screen appearance
of the Enif program.
- Font parameters which allow the customization of the
fonts used by Enif.
- Stylus parameters containing the system defined styli
and an open set of user defined styli.
- Network caching parameters which are used to determine
which network attributes are put into the network element's data buffers
and which are read ``on-the-fly'' from the EMME/2 data bank when needed.
- Plot related parameters controlling the features of
the network plane (e.g. magnifier size and factor) and defining whether
the network uses right hand or left hand traffic.
- Print parameters are used to setup the
printing characteristics used for plots and lists.
- Predefined views allow the user to store and recall network
windows to easily access a certain part of the network plane by a logical
- Registered plot and list configurations are used to
define which plot and list configurations can be accessed directly
from Enif's ``Plot'' and ``List'' menus.
The values of all preference parameters can be saved to an
so that they can be used as starting values for subsequent Enif sessions.
By default the initialization file enif.ini is used, but
it is also possible to specify an alternate initialization file
on the Enif command line using the
