What Paul was saying is that how the examine command is displayed is up to
details implemented in individual simulators, but that there is some attempt to
have switches which mean the same thing from one simulator to another. See:
sim> HELP EXAMINE SWITCHES
Beyond the standard switches, the PDP11 simulator interprets the -B switch to
mean display bytes since the machine, although byte addressable, is a word
oriented machine. See: doc/pdp11_doc.doc for more details as well.
