DEBUG MONITOR COMMANDS
M68CPU32BUG/D REV 1 3-28
HE Help HE
3.14 HELP
HE [<command>]
HE is the CPU32Bug help facility. HE <CR> displays all available commands and their title
plus any macro commands that have been defined (see macro define/display (MA) command).
All CPU32Bug commands are in alphabetical order except for NOxx and the "alias" commands.
Macro commands are displayed first, in the inverse order in which they were defined. When the
HE command output fills the terminal screen, a message is printed asking the user to press
"RETURN" to continue. Entering he <command> displays the specified command name and
title.
