SECTION I

SYSTEM OPERATOR'S CONSOLE

The operator communicates with the Time Shared basic System through an
ASR-35 teleprinter console.  From this console the operator can control and
monitor user access to the system, modify or examine the directory of disc
usage, change the hardware configuration on-line, check who is using each
terminal, and systematically shut down the Time Shared Basic System.  The
computer, disc, and photoreader reside in a locked cabinet.

CONSOLE OPERATION

When the Time Shared Basic System is loaded into the computer, check that the
ASR-35 teleprinter is set to LINE.  See Figure 1-1.




                      Figure 1-1.  On-Off Switch

Three of the settings of the Mode Switch on the teleprinter are usable with
the Time Shared basic System.  These are the "K", "T" and "KT" positions.
When set to the "K" position, the teleprinter will print only, not punch.
When set to "T", the teleprinter will both print and punch everything that
goes through it.  The "KT" position is the normal setting; in this position
only the LOG ON* and LOG OFF messages are punched.  See Figures 1-2, 1-3,
and 1-4.

* See Section VI LOGGING



If Switch Register bit 0 on the front panel of the computer is in the up
position, all input from the console will be ignored by the system.  With
this feature, if the cabinet door is kept locked, unauthorized persons can be
prevented from tampering with the operation of the Time Shared Basic System.

OPERATOR COMMANDS

The operator maintains control of the system by means of Operator Commands.
The format of all these commands is identical.  Only the first three letters
of each command are significant; the remainder are superfluous and need not
be included.  If the command requires parameters, the character dash ("-")
must separate the command and the parameters.  Parameters are separated by
commas (",") and blanks are ignored, except in the SLEEP Command. Each com-
mand is terminated by a carriage return.  If the system does not understand
a command, it will print ???.

The character _ acts as a backspace key.  Typing this key causes the com-
puter to delete the previous character.  For example, the sequence:

                ABC__DE_F

is equivalent to the sequence:

                ADF

Either of the characters ALT-MODE or ESCAPE deletes the entire line being
typed.  When the system senses such a character it automatically responds
with the character "\", followed by a CARRIAGE-RETURN and LINEFEED.

All numerical communication with the Time Shared Basic System is in decimal,
except for I/O select codes necessary for the hardware configuration com-
mands.  These are in octal.  Disc track numbers are in decimal.



Table 1-1 lists the Operator Commands alphabetically, with their functions
and where they are documented.
