You can also run GDB in text command mode, like the other debuggers
in Emacs. To do this, replace the GDB @code{"--annotate=3"} option
with @code{"--fullname"} either in the minibuffer for the current
Emacs session, or the custom variable @code{gud-gdb-command-name} for
all future sessions. You need to use text command mode to debug
multiple programs within one Emacs session. You can also use
@kbd{M-x gud-gdb} to invoke GDB in text command mode if you have
problems before execution has started.
