Syntax
The RESTART: command, which has no arguments, is used to restart
the program afresh, with the particular exception that any external files
introduced when starting the program, or later via the
CHANNEL: command, are left alone. Consequently, any macros and
so forth remain available after the restart.
If the program was started
initially with a log-in macro on a file on channel 1, this macro is not re-run.
The history
buffer is flushed to a history file if one has been defined, and the
buffer is then emptied, and the storage of screen commands is switched
off. The output channel is reset to the screen.
The CLEAR: command is similar, but does not interfere with
either currently-defined loops or the handling of macros.
