1 SECURE
.BR
When leaving a terminal unattended,
it is sometimes desirable to render it unusable by anyone else, but inconvenient
to log out. The SECURE command clears the screen, fills it with a message
saying you are out, and waits for you to enter a password.
.p0
While you are away, any messages broadcast to you are recorded using the
BROADCAST/RECORD command (q.v.). They are replayed, by issuing a BROADCAST/LIVE
command when you enter the correct password (unless
broadcast recording was already on when the SECURE command was entered).
.p0
The command format is:
.s.i5
$ SECURE [name] [message] [back] [password] [logout]
.br.rm74
2 Parameters
.br
3 Name
.br
The name parameter is your personal name. If you omit it, or supply a null
string, your current username is used instead.
.br
3 Message
.br
A one-line message which may be used to indicate where you can be found. If
you do not enter a message, the string OUT is used instead. The message is
displayed in double-width characters, and should therefore be no longer than
half the screen width.
.p0
There are two special cases:
.s.i5
LUNCH######is translated to "at lunch"
.s.i5
COMPUTER###is translated to "in the Computer Room"
.br
3 Back
.br
A message indicating when you expect to be back. This is displayed on a line
as:
.s.i5
Back:#####back__message
.p0
If you do not supply a back parameter, or supply a null string, no message,
or "Back:" prefix, is displayed.
.br
3 Password
.br
A password of one or more characters, without distinction between upper- and
lower-case letters. If you do not enter a password, you will be prompted for
one. Passwords entered to prompts are not echoed.
.br
3 Logout
.br
Y to specify that another user wanting to use the terminal may log you out by
pressing ctrl/C or ctrl/Y. If you permit this, a message to the effect is
displayed at the bottom of the screen. N (the default) does not permit a logout;
no message is displayed, and ctrl/C and ctrl/Y are ignored.
