It should run on any terminal that recognizes ANSI escape sequences. On a workstation, the screen interface will look best if you use a window set up for light text on black background. The small version requires 16 Mb RAM and the large one requires 28 Mb. In a VMS or UNIX distribution, the large version is the default. If you have less than 32 Mb physical RAM, you may get a substantial performance increase by using the small version.
Qualifiers are case-independent.
This convention is therefore used in the descriptions below. To reduce errors in the average background due to quantization and roundoff, the background image is normally scaled by a factor of 64 relative to the background on the input frames. In rare cases, it is possible for the background pixels on input frames to exceed 512, exceeding the 32K range of the background image. If the entire has table is not physically resident, performance suffers substantially. If you have a monochrome terminal, menu items will be highlighted in revers, bold, etc. rather than in colors.
