- 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.
