Before ending your session, you may choose to print
out all of your recorded transcripts. If you type 'y', the
program will send your transcript to an appropriate printer
In either case, the transcript will be saved in a file
with the format XXX.chemtab where XXX is the process ID
of your current session.
_
Since you have selected some elements within
certain boundaries, now you may choose whether or not you
wish to use all the elements or these special elements
when plotting on the graph. Type 'a' for the special
elements, or 'b' for all the elements.
_
In order to graph, each axis must have a
definition. If you want to compare electronegativity to
atomic number, it is easier to see the pattern if atomic
number is on the x-axis, (which is also the wider axis
with 69 [or 600 with ReGIS].)
_
The x-axis is special because it is the scale for
what you view. You can change this scale to be whatever
you wish. If you only want to look at elements with an
atomic number between 50 and 60, you can select atomic
number for your x-axis and enter 50 for the x-axis
minimum value, and 60 for the maximum.
_
In order to graph, both axes must have a
definition. The y-axis is important because this will be
what you are comparing to. You must choose one. Example:
If you choose atomic number for both x- and y-axes, you
should get a straight line slanting /
_
The ReGIS graphics can provide you with grid lines
at the intervals marked on the screen. This helps in
determining a point's values on the graph far away from
the axes.
_
Sometimes it is easier to see a pattern if the
points are connected. An example is atomic number vs.
electronegativity. Try it and decide which you like
more.
_
This is only for asthetics and speed. The points
look nicer on the graph but they take longer because they
are a 'graphic fill' which only means it takes more time
for the terminal to do the work than it would to make two
lines.
_
This is the first sub-menu. Here you can choose
which method you want to look for an element by. Your
choices are name, number, or symbol. Of course you can
get back to the main menu by hitting '4'.
_
Type in the full name, or part of a name of an
element. If your choice is not ambiguous, ('i' would be
ambiguous, whereas 'hyd' would not) the computer will
display the information you request.
_
Type in the atomic number of the element you
are looking for.
_
Type in the symbol of the element you are
looking for. Remember that uppercase and lowercase
count here.
_
The computer can keep a copy of all lists,
graphs (not ReGIS graphs), and tables (not VT100
alternate set tables) which you make. These will
be saved in a file in this account and you may
have the option to have this program print these
out for you.
_
Since there may be more than one person
printing out at a time, this program will put your
name on the top of your transcript so you can tell
which one is yours.
_
This is the main menu. From here you can
do several things. '1' will let you choose to
look at one elements information. '2' will allow
you to choose boundaries for the elements you wish
to look at. '3' will list these special elements.
'4' will show their position on the periodic table.
'5' will let you use the graphing module.
'6' will exit the program. '^R' or Control-R
(hold down the control key and press R) will turn
ReGIS mode on and off. This affects the graphing
portion of the pogram only. Of course, '^C' will
exit the program at any time. '^V' shows all version
definitions.
_
For asthetics, the program can make the
periodic table look nice by using graphics.
One drawback is that these graphics cannot be saved
and printed.
_
Here you should choose one characteristic
to set. Say, for example you want to see all
elements with a melting temperature greater than
1000 celcius. You would type in the number for
melting temperature here.
_
_
The ReGIS commands can be printed on any DEC
LN03 compatible laserprinter, possibly others. If
you want the program to save a copy of your graph
in text form (usually about 5000 chars) type 'y'.
The filename will be in the current directory under
'laser'.
_
This determines how your search will be
processed.
_
_
You may choose whether or not you want this
graph, list, or table in your transcript.
