The parameter menu

Another collection contains the parameter options f7, which can be chosen by moving the cursor. Single line extracts from these three panels can be viewed by using the cursor arrows or the page and paragraph keys, just as though one were using one of the popular text editors. Finally, keys f9 and f10 govern the color palette; this allows individual bitplanes to be viewed and agreeable (or even disagreeable) colors to be chosen.

• 1: atern - alternate rule

In greater detail, the significance of each parameter is the following.

• 1: atern - Chooses alternate lookup tables for the Moore neighborhoods when they exist; range 0-4.

• 2: wfrno - A number in the range 0-255 which is the Wolfram rule number for the one dimensional binary automaton option.

• 3: hdens - The density (mils) of live cells for the option c.

• 4: mdens - The density (mils) of live cells for the option R.

• 5: ldens - The density (mils) of live cells for the option p.

• 6: wdens - The actual number of dots for the option w.

• 7: elrad - The radius (in units of about 6 pixels) of the ellipse for option y; range 0-54.

• 8: nchek - The number of checkerboard squares for option k.

• 9: tacol - The number in the range 0-255 used by videocattr to display table entries; it combines foreground and background.

• 10: macol - The number in the range 0-255 used by videocattr to mark table entries; it combines foreground and background.

• 11: cucol - The number in the range 0-255 used by videocattr as a cursor when displaying tables; it combines foreground and background.
