As commands are typed to the Interactive Monitor they are echoed on the user's terminal. When a
command, or field, is recognized
as
unique by the command processor it is automatically carried
out on the user's terminal. Arguments or options can then be selected. Arguments are terminated
by pressing the <Enter> key. Some command strings must be terminated by pressing the <Enter>
key
to
execute the command, others execute immediately when recognized.
When a mistake
ha
s been made, pressing <Control-C> (Press the <CTRL> key while simultane-
ously pressing the character 'C
')
will result in the command line being discarded. The command
processor will print the message 'Canceled' on the user
's
terminal as an indicator that the command
has been discarded.
Whenever a character is typed that
is
illegal in the current context, then the character is ignored and
the <Bell> is echoed. The <Bell> is a signal to the user that an invalid character has been entered.
The execution
of
any command can be interrupted by typing <Control-C> at any time.

Command Descriptions
The following paragraphs describe the individual commands and their associated options. Gener-
ally each command can have 0, 1
or
2 options. These options may be keywords or arguments.
Keywords are entered and recognized by the command processor as commands. That
is
, when the
system recognizes what keyword
is
being entered, the option
is
completed automatically by the
command processor.
Arguments are one
of
three types: numeric, ASCII, or
MDR
BCD.
Numeric arguments fall into 3 classes: addresses, values, or repeat counts. Addresses range from
0
to FFFFFF hexadecimal, values range from 0 to
FF
hexadecimal,
and
repeat counts range from 0 to
65
,535 decimal. Unless otherwise noted, omitted numeric arguments default to
0.
ASCII arguments can be any character that the keyboard can generate. Characters that are not
printable are echoed as '.
',
the period. When an ASCII argument
is
omitted the default
is
NULL.
