RPB$V _CON'v - Conversational boot. At various points in the
system boot procedure, the bootstrap code solicits parameters and
other input from the console terminal.
If the DIAO is also on, the
diagnostic supervisor then enters MENU mode and prompts the
user for devices to test.
RPB$V _DEBUO - Debug. If this flag is set, VMS maps the
code for the XDELTA debugger into the system page tables of the
running system.
RPB$V _IN1BPT - Initial breakpoint. If RPB$V
_DEBUG is
set, VMS executes a BPT instruction immediately after enabling
mannina
