8.74 HST (History of commands)

8.74.1 Function

The HST command displays a list of the last commands entered from the command line. Usually every
issued command is automatically added to the command recall history list. To prevent a command from
appearing in the command recall history list it must be prefixed with a hyphen (‘-‘) to make it a silent non-
echoing command.
