ADVDISP is context file driven. Application parameter/keyword defaults reside in the file(s) ADVDISP.CORE, ADVDISP.SITE, and ADVDISP.USER. The program will use default values from only one of these files. The program will scan for context files in the order .USER, .SITE and finally .CORE. Once an ADVDISP context file is located, all of the defaults defined in that file are used by the application.

If a default value is not specified for the above Parameters and Keywords, the defaults are enumerated in the context file(s) for each specific display name.

COLors can be specified as either "relative" pen numbers or "absolute" color names. For example if the standard McIDAS graphics enhancement is set for the display frame, you could specify either COL=RED or COL=5 to draw an advisory outline in red. When using absolute color names the color name must be defined for the frame you are plotting.

When drawing the line segments of an advisory, intermediate points along the the path from the beginning segment point to the ending segment point are computed using a great circle approximation.

This program is a variation from code contributed by the Johnson Spaceflight Center (ADVSRY).
