If the PC loses power, is turned off or rebooted, Arc can re-run the program that was running. This is great for BBS, fax machines etc that have to remain on all the time. Can have items that don't return to Arc after running. Very useful for logout options on a network. Can have items pause after running - to show you the output.
Items can prompt for log comments before running.
Very useful for keeping track of billing information. Extensive on- line documentation for errors that can occur while interpreting these commands. Environment variables can be edited . Built-in screen saver . You can also use your own screen saver, disk unfragment program, tape backup, virus scan etc.
