I guess I lost the original versions of continuemove and redomove by overwriting a newer file with an earlier file. So I rewrote them, doing it differently this time, because I didn't remember exactly what I did before. But the functionality should be the same. Continuemove is another name for extendmove. Redomove is just like continuemove except that it does not retain any past moves. They use the same code, differing only in what they set the pastmovesfield string to. I am using the names continuemove and redomove to reflect their similarity to the continue and redo commands used for loop control. Like these commands, they are used for a kind of loop control, except that instead of the loop existing inside a single program, the loop is between moves executed by different programs. Like continue and redo, unconditional or improper use of continuemove and redomove can create infinite loops.
