Each of the tables has a cursor, consisting in illuminating its table entry with a distinct color; to determine the value of the table at that position, it is only necessary to type the number of the state. The cursor will advance automatically, except that it will not change rows when there are more than one.
The cursor can be positioned without altering any states by using the arrows; space and backspace can also be used. If a mouse is available and programmed to emit arrows, that is another way to position the cursor.
Creating a table on the screen sets up a data table in the program's data space, but does not place it in the CAM . The tables persist throughout a CAMEX session; changing demonstrations always leaves the tables of previous demonstrations intact, so that it is always possible to return and continue without interruption.
However, the bitplanes and the tables may have changed during the interim; INSERT will install the table at any time, either to continue a previous experiment, or to set up the table which has just been edited.
Another special case, e, is one in which a cell joins its neighbors whenever all three of them agree. But the agreement, if any, is transitory and keeps shifting.
