(positive) to non-plotting (negative) and vice-versa. When an atom is
deleted, all bonds to it are also deleted. Deleted atoms are not instantly
removed: the changes in plot status are not put into effect until the drawing
is replotted, by pressing ENTER or with options [L.7] or [D].
A polyhedron can be deleted only by changing the sign of the central atom. If
the sign of the central atom is negative, none of the ligands will be plotted
either. However, the sign of the ligands determine whether bonds to them are
shown or not. When you turn off a polyhedron by changing the sign of the
central atom, the signs of the ligands are also negated; turn the bonds from
other atoms to the ligands back on by changing the sign to positive again.

If you choose a window, the entire image, as shown on the screen, will be
compressed into a specified area (window) on the output page. You must
specify the size of the window, and the location of the upper left corner.
The size and location, in inches, are in "page" coordinates; on a printed
page, the origin is in the upper left, the first or x axis extends to the
right, across the page (short dimension), and the second or y axis extends
down the page (long dimension). Thus a displacement of 0,0 prints the image
in the upper left corner, x,0 prints it x inches to the right, etc. You have
the option to rotate the image 90 degrees, so that it is upright for normal
printed page orientation; if it is not rotated, it will be in the same
sideways orientation as the full-page printout.
When a laser plot or a printer file in laser format is finished you will be
asked if you wish to send a printer reset, which is essentially the same as a
form feed. If you decline to use this, you can put any number of plots on the
same page. With impact printers, you will have to manually back up to the
starting point or re-insert the paper to plot more than one image.
OUTPUT FILES. There are two types of dot-matrix output files: printer-command
files and image files.
PRINTER-COMMAND files simply store the commands for the printer which is
currently selected (option [M.1.2]). You can later cause the image to print
out (on a letterhead, for example), with the DOS command
COPY/B filename PRN
See the instructions (option [I]) for printing out and relocating the drawing
on the page.
IMAGE files (e.g. .IMG, .PCX files) contain bit-mapped data in certain formats
which can be read by various "paint" programs which allow modification of the
image, or by publishing or word-processing programs which can incorporate the
image in a printed document. If you choose one of these formats, the plotting
will be done as if it were in the 300 dpi laser mode, which means that 7
passes are required for a full page. Thus a full page may take up a great
deal of disk space, although all these file formats have some form of data
compression. There is no relocation of the images in these files. The files
contain black-and-white data only; if you want a color file you will have to
use an image capture program, examples of which are often supplied with paint
software, or can be obtained from shareware distributors.
