- virtual int do_execute(void) - the `heart' of each class
derived from Command. This function performs the required task
(if possible), and returns TRUE if successful, FALSE if there is an error.
When errors occur, messages should be printed to msgErr in this
function, and preferrably NOT within the lower-level objects (i.e. the
Molecule or DisplayDevice objects).
- virtual void create_text(void) - formats the text equivalent
of the command, writing the text to the cmdText stream.
