3) Some commands are discussed together for conveni-
ence. In these cases, a slash (I) separates the
commands.

4) Memory addresses may be shown with the segment
enclosed in < and >, with the offset immediatly
following. <1>0 refers to segment 1, offset o.
5) Command parameter values retain their previous
values until changed. Most parameters have
default values, described in the command descrip-
tions below. Some parameters are shared by more
than one command.
Example: The following commands all share the
write buffer start address parameters,
wseg and wo ff:
a) WR wseg woff Inth cyl head sec
b) SWSEG wseg
c) SWOFF wo ff
