INT _ _ _ _ _ _ _ _ _ _ _ _ switch

The int switch specifies an interactive mode of operation. Default on.

There is no reason to turn int off during interactive calculations, since there are no benefits to be gained. If you do have int off while inputting a file, and REDUCE finds an error, it prints the message ``Continuing with parsing only." In this state, REDUCE accepts only end; or bye; from the keyboard; everything else is ignored, even the command on int.
