Description
This command enables you to edit or plot the library of opening/end
condition combinations.

Since each combination is associated to a specific wall and opening
type, you must specify both, using one of the following options:
the currently active wall or current default opening option `c'
the name of the wall or opening option `n' indicate an existing wall or
opening on screen  option `i' select the wall or opening from the respective
graphic library  press <ENTER>

If you select option `i' or `n', indicate and confirm the wall and
opening, or specify the name, respectively.

Option `e' edit (opening/end condition) combination library

The screen is replaced by a temporary file called $C$LIB. Initially
this file consists of eight options, a rectangle showing a sample
of the specified wall, a white square containing the system end condition
and additional white squares containing further end conditions that
have been included in the end condition library using the \elib
command.

The eight options on the screen are as follows:

DEFAULT PLACE
DELETE  ADJUST
SAVE    ENDCOND
QUIT    ACCEPT

If opening/end condition combinations already exist, they will be
displayed in a series of squares above those containing the individual
end conditions. These squares may be either green, red or blue.

Green squares will be active in the combination library and will be
available for placing.

Red squares will be inactive in the combination library and will not
be available for placing.

A blue square indicates the current active default combination.

By moving the cursor over the red or green squares and pressing B1
of the mouse, you may reverse the status of the openings from active
to inactive and vice versa. The color of the square changes accordingly.

PLACE

When you select the place option, the specified opening, attached
to the cursor, appears within the sample of wall. You may "slide"
it along the wall by moving the cursor. You may change the orientation
of the opening by pressing <Alt>+1 which switches the symmetry
of the opening between its four possible orientations. You are prompted
to position the opening in the wall by pressing B1 of the mouse. Once
positioned, the opening "breaks" the wall.

You may create several combinations for the same wall and opening
type. For example, you may require the same combination with a different
opening orientation or different end conditions. To create the next
combination press B1 of the mouse while the cursor is on the PLACE
option. The end condition displayed on the wall sample will be deleted
and you may then repeat the combination process.

ENDCOND

If you wish to attach an end condition to the opening, move the cursor
onto the ENDCOND option and press B1. Then move the cursor

onto the required end condition and click B1 again. Indicate the wall
on the side of the opening to which the specified end condition is
to be attached. Repeat this process for the second side. The end conditions
for both sides do not have to be identical. The system will place
the end conditions on either side of the opening with the correct
symmetry.

ACCEPT

If you are satisfied with the combination that you have assembled,
press ACCEPT and confirm your acceptance. You may add a description
of up to 40 characters. Spaces (created by pressing the space bar)
are illegal in the description text. Use the underscore (_) in place
of spaces. If you do not wish to give a description, press <ENTER>.
The new combination will be added as a new square at the top of the
drawing.

ADJUST

In certain cases you may find that the opening is not suited to the
wall, i.e., incorrect wall thickness or its position within the wall

thickness. In this case you may adjust the opening. Move the cursor
over ADJUST and press B1. You may now move and adjust the location
of lines and points within the opening by selecting one of two options
that operate in a similar way to the commands \movef
and \movep. The movement is limited to the opening only.
You do not have to be concerned about picking other parts of the drawing.

NOTE: You may use nested commands while working in this environment.
You may find commands such as \zoom, \zout and \prvs especially useful at this
stage.

When the opening has been adjusted correctly press <ENTER>.
You may then attach end conditions if you have not done so already.
Accept the combination or select any of the other options. You may
exit the adjust option by pressing B3 of the mouse and then <ENTER>.

DEFAULT

Move the cursor over DEFAULT and press B1 of the mouse. Indicate
the combination that you want to be the current default. You are asked
to confirm the selection. The color of the square enclosing the selected

combination changes to blue, and the previous default changes to green.

DELETE

Move the cursor over DELETE and press B1 of the mouse. Indicate
the combination that you wish to delete. You are asked to confirm
the selection. The color of the square enclosing the selected combination
changes to yellow and will be deleted when you save the library.

NOTE: When a wall is deleted from the wall library
or an opening is deleted from the general opening library, all combinations
that use these entities will be deleted from the combination library
and the library will be compressed.

SAVE

When you have finished editing the combination library, move the cursor
over SAVE and press B1 of the mouse. Confirm saving the changes
you have made to the library. You are then asked if you wish to edit
further combinations for other openings. If you wish to do so you
will be asked to specify another opening.

QUIT

If you regret the changes that you have made and wish to ignore them,
move the cursor over QUIT and press B1 of the mouse. Confirm
quitting the library without saving the changes you have made to the
library. You are then asked if you wish to edit further combinations
for other openings. If you do, you will be asked to specify another
opening by any of the four means described above.

NOTE: If you select QUIT all new combinations
will be lost even if you used the ACCEPT option.

Option `p'  plot the combination library

This option enables you to create a plot file for the opening types.
Confirm creating the file and provide a name of up to eight characters.
You are then prompted to create further plot files for other opening
types.

NOTE: The screen display during this command is an
ordinary drawing file created by the system. It is named $C$LIB (.III
and .DDD). You may use nested commands such as \zoom,\zout
and \shift, etc. This is a temporary file and will be
erased when you leave the system. You should always leave this command
via the SAVE or QUIT options. If, by mistake, you use
a non-nested command and find that you cannot exit the command, use
the \rslib command.
