DISABLE
Syntax: DISABLE BORDER
Default: enabled
This means that the rectangular borders that delimit the hardcopy page
boundary and the window edges will not be drawn. These rectangles do not
appear on any hardcopies, but may be considered to interfere with the
monitor display.
Syntax: DISABLE BROADCAST
Default: the state of the terminal when PHYSICA was invoked
The DISABLE BROADCAST command is equivalent to the DCL command:
$SET TERMINAL/NOBROADCAST
This controls whether or not a broadcast message will be accepted by the
terminal. Enter DISABLE BROADCAST if your are not interested in receiving
broadcast messages such as ``New mail''.
Syntax: DISABLE CONFIRM
Default: enabled
This means that no confirmation will be requested when text and figures
are drawn. This confirmation setting can be overridden on specific
commands by using the \CONFIRM qualifier.
Syntax: DISABLE ECHO
Default: disabled
This means that commands that are entered via a command macro file will
not be displayed on the monitor screen as they are executed.
Syntax: DISABLE HISTORY
Default: enabled
If HISTORY is disabled, when a variable is altered, it's history will not
be updated. A variable's history is displayed with the SHOW command. This
feature was included because variables altered within large do loops were
having their histories updated so many times that virtual memory limits
were being exceeded. Even if HISTORY is disabled, new variables will
still have initial history lines. See also SHOWHISTORY and MAXHISTORY
in the SET/GET command sections.
Syntax: DISABLE JOURNAL
DISABLE JOURNAL\MACRO
Default: enabled, journal file: PHYSICA.JOURNAL, macro journaling disabled
DISABLE JOURNAL means that the journal file is closed. Subsequent journaling
of program output and user input will be disabled. DISABLE JOURNAL\MACRO
means that journaling of macro commands ONLY is disabled.
If JOURNAL is enabled, the DISPLAY string command will write the string
to the journal file the same way it is written to the monitor screen.
If JOURNAL\MACRO is enabled, the DISPLAY command itself will ALSO be
written to the journal file.
See also the JOURNAL command.
Syntax: DISABLE PROMPTING
Default: enabled
This means that you will not be prompted for input when you leave
something out or enter some incorrect parameter.
Syntax: DISABLE REPLOT
Default: enabled
This means that subsequent graphs and text will not be stored for
replotting. See the REPLOT command for more information.
Syntax: DISABLE REPLAY
Default: enabled
This means that the X Window System graphics replay storage is disabled,
hence subsequent graphics will not be available for replay. For example,
if the graphics window size is changed, the graphics displayed in that
window will not be re-displayed. The virtual memory space for storing
graphics vectors is allocated dynamically. Enter DISABLE REPLAY to save
virtual memory space for other uses, such as large data arrays. The
REPLAY keyword only applies if an X Window System type monitor is being
used. See the MONITOR command for more information.
Syntax: DISABLE SHELL
Default: enabled
This means that the input line recall shell is disabled, and you will not
be able to recall keyboard input lines. When the SHELL is re-enabled, the
buffer of input lines will be available again. It is useful to disable the
shell when reading data across a network, since the terminal I/O may become
corrupted if the shell is enabled. See the BUFFER command for more
information.
Syntax: DISABLE STACK
Default: disabled
This means that subsequently entered commands will not be written to the
specified stack file. See the STACK command for more information.
