• Execute commands from a file.

The "load" command has two related uses; it is used to restore "save"d files, and to run scripts of pre-written commands.

The "verbose" option forces display of the file's source lines.

Loading a file does not REPLACE the current session; the saved commands MODIFY the current session just as if they had been entered interactively.  If the script requires a clean slate, "unlock all", "clear all", and "remove all" commands should be included early in the script.

Scripts can contain "comment"s and include interactive elements such as the "input" command.

Note:  Scripts can load other scripts, so they can access related library files of equations and variables automatically.
