UNSET

Unset various shell parameters.

SYNOPSIS

unset [ ( echo | noexecute ) ]

This command allows the user to turn off several useful shell parameters. The command set allows the same parameters to be turned off.

echo: Turning off the echo option turns off echoing the command buffer. This is usually the desired setting (and the default) when entering commands interactively as opposed to when commands are taken from a file.
noexecute: The noexecute flag when off sets all commands to normal mode. They parse and examine parameters and will execute the command if they have legal data.

The parameters all have to be typed in full. The parser does not understand shortened versions.
