At the CPU32Bug> prompt, enter SD to switch to the diagnostics directory. The Switch
Directories (SD) command is described elsewhere in this chapter. The prompt should now read

Command Entry and Directories

Enter commands at the CPU32Diag> prompt. The command name is entered before pressing the
carriage return <CR>. Multiple commands may be entered. If a command expects parameters
and another command is to follow it, separate the two with an exclamation point (!). For
instance, to execute the MT B command after the MT A command, the command line would read
MT A ! MT B. Spaces are not required but are shown here for legibility. Several commands may
be combined on one line.
Commands are listed in the diagnostic directory. Some commands have sub-commands which
are listed in the directory for that particular command (see example below).
