(i.
e.,
the
command's
name,
what file names must be specified, and what
options are available) of the most frequently used
commands.
PART II
gives a complete and detailed description of
all
MDOS
commands.
In addition, Appendix
H
contains a summary of
the
command line formats of all MDOS-Supported software products.
Most
frequently a "space" is used to separate <name 1>,
the command name,
from the other names
which
are
typically
separated
by
"commas".
The "semicolon" always separates the
options from the rest
of
the command line.
The
"space"
and
II
comma"
are
the
recommended separators since they make the
command line the most readable;
however, any
character
that
will
not
be
mistaken
for
an
MDOS
file name character, a
suffix delimiter, a
logical
unit
number
delimiter,
01'
a
device
name
delimiter
(see section
2.7.1)
can be used as a
separator.
The
use
of
special
characters,
although
pe-r'mitted,. is
not
recommended
because
the
command
line
becomes very unreadable.
2.5
System Console
The system console is used as the communications
device
between the operator and the
operat~ng
system.
MDOS messages
are displayed on the console printer
or
display
mechanism.
MDOS
commands,
as
well
as operator inputs prompted
by
the
commands, are entered via the
keyboard.
All
command
line
input
and
most input to the various commands requires upper
case, alphabetic cha-racters.
Numeric and special characters,
of
course, are case independent.
To allow corrections to be
made to any typed line before the terminating carriage return
is entered, several special keys on the keyboard can be used.
In addition,
two other
special
keys
serve
to
prematurely
abort
a
command
in
p-rogr-ess or to "freeze" the display of
messages on the consoie.
2.5. 1
CaT'riage return key
The
CARRIAGE
RETURN
key
is
used
to
terminate
any
operator
response
to
an MDOS input
p~ompt.-
This
is
true ror
the command line as well as
all
other
input
that
may
be
required
fT'om

operator
by
the various commands.
