ENABLE
Syntax: ENABLE BORDER
Default: enabled
This means that the rectangular borders that delimit the hardcopy page
boundary and the window edges will be drawn. These rectangles do not
appear on any hardcopies, but may be considered to interfere with the
monitor display.
Syntax: ENABLE BROADCAST
Default: the state of the terminal when PHYSICA was invoked
The ENABLE BROADCAST command is equivalent to the DCL command:
$SET TERMINAL/BROADCAST
This controls whether or not a broadcast message will be accepted by the
terminal. Enter ENABLE BROADCAST if your want to receive broadcast
messages such as ``New mail''.
Syntax: ENABLE CONFIRM
Default: enabled
This means that confirmation will be requested when text and figures
are drawn. This confirmation setting can be overridden on specific
commands by using the \NOCONFIRM qualifier.
Syntax: ENABLE ECHO
Default: disabled
This means that commands that are entered via a command macro file will
be displayed on the monitor screen as they are executed. If ENABLE ECHO
is encountered within a command macro, echoing is enabled only for that
macro. For example, suppose you have echoing disabled at the keyboard
entry level and you execute a macro which has ENABLE ECHO within it.
Subsequent lines from that macro will be echoed, but when that macro is
finished executing, echoing will be disabled again.
Syntax: ENABLE 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.
Syntax: ENABLE JOURNAL
ENABLE JOURNAL\MACRO
Default: enabled, journal file: PHYSICA.JOURNAL, macro journaling disabled
ENABLE JOURNAL means that subsequent journal entries, that is, program
output and user input, will be appended to the last journal file that was
opened. Commands read from a macro file will not be journaled. Use:
ENABLE JOURNAL\MACRO to also journal these macro commands.
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: ENABLE PROMPTING
Default: enabled
This means that commands will prompt you for input when you leave
something out or enter some incorrect parameter.
Syntax: ENABLE REPLOT
Default: enabled
This means that subsequent graphs and text will be stored for replotting.
See the REPLOT command for more information.
Syntax: ENABLE REPLAY
Default: enabled
This means that the X Window System graphics replay storage is enabled,
hence subsequent graphics will be available for replay. For example, if
the graphics window size is changed, the graphics displayed in that window
will be re-displayed. The REPLAY keyword only applies if an X type monitor
is being used. See the MONITOR command for more information.
Syntax: ENABLE SHELL
Default: enabled
This means that you can recall keyboard input lines using the arrow keys.
See the BUFFER command for more information.
Syntax: ENABLE STACK
Default: disabled
This means that subsequently entered commands will be appended to the last
stack file that was opened. See the STACK command for more information.
