| GRAPHER2, version 2.01 |
+----------------------------+
+============================================================+
| Notice Regarding Hercules Adapters |
| |
| GRAPHER2 version 2.0 had a bug that would cause the |
| program to rudely abort when run on a computer using |
| a Hercules graphics card. This version of GRAPHER2 |
| fixes that problem. To all users of GRAPHER2 who |
| experienced that problem, our most sincere apologies. |
+------------------------------------------------------------+
Installing GRAPHER2 on a floppy diskette
----------------------------------------
If your computer does not have a hard disk then place your system
diskette (the diskette you "boot up" with) in drive A:, and a
formatted diskette in drive B:, then type the command,
DISKCOPY A: B:
After DISKCOPY displays its message "Strike Enter when Ready", then
remove the system diskette from drive A:, place the GRAPHER2 diskette
into drive A: and press the enter key.
Note: If your computer has only one floppy drive then you need only
type, "DISKCOPY".
Now, place the MS-DOS diskette that contains the file GRAPHICS.COM
into drive A: and, for two floppy systems, type,
COPY A:GRAPHICS.COM B:
If you have a single floppy systems, type, COPY A:GRAPHICS.COM A:
and when DOS is done with the copy, then type, COPY A:GRAPHICS.COM A:
The GRAPHER2 diskette that you have just created is ready to be used.
Installing GRAPHER2 on a hard drive
-----------------------------------
Create a directory for the GRAPHER2 utility. You can name this
directory as you wish (LSRGroup suggests that you name the directory,
\GRAPH). Once you have decided on a name for your directory, at the
DOS prompt, type the command "MD \GRAPH" (assuming GRAPH is the sub-
directory name you have chosen). Then, copy all the files from the
GRAPHER2 diskette to this directory. Example:
COPY A:*.* C:\GRAPH
Loading GRAPHER2.EXE
--------------------
Be sure that your current drive and directory is the default drive
and directory for GRAPHER2, then, at the DOS prompt type,
GRAPHER2
If you plan to make printed copies of your graphs, before you issue
the command to load GRAPHER2, you must load the DOS utility called,
GRAPHICS.COM. Simply type, GRAPHICS, then press the Enter key, then
type GRAPHER2, and again press the Enter key.
GRAPHICS.COM remains in memory. Therefore, so long as your computer
remains on, you do not have to load GRAPHICS again.
Loading GRAPHER2 on Hercules Systems
------------------------------------
If your computer uses a Hercules graphics card, GRAPHER2 needs to
have the utility called SIMCGA loaded first. Run GRAPHER2 by typing
the command, HERCGRAF. This batch file loads SIMCGA, then runs
GRAPHER2, and then unloads SIMCGA by running RMVCGA. The batch file
can be modified to run MONO in lieu of RMVCGA.
If your computer uses a Hercules graphics card and you already have
SIMCGA installed, then run GRAPHER2 by typing, GRAPHER2 HERC.
If you don't have SIMCGA, then you should down-load it from your bbs.
If you plan to make printed graphs, before you load GRAPHER2, you
must load the DOS utility, GRAPHICS.COM. Simply type, GRAPHICS, then
type HERCGRAF.

Revisions
---------
GRAPHER2, version 2.0, is a complete re-writing of the earlier version
called GRAPHER, version 1.0 and contains a Lotus-like spreadsheet for
the keyboard entry routine, allows 144 data points, and allows posi-
tive and negative numbers for all charts except the line chart.
Version 2.0 includes an improved import routine for importing and up-
dating previously created data tables. The improvements to the import
routine allows you to import any block of data and to position it
anywhere within GRAPHER2's spreadsheet. Also, version 2.0 allows you
to save the graphic images as disk files, and sends a form feed after
printing any chart.
GRAPHER2, version 2.01, contains seven changes over version 2.0:
1. Version 2.01 increased available string space by approx-
imently 1200 bytes.
2. Version 2.0 would only read DIF files created from earlier
versions of Lotus 123. Version 2.01 corrects this and now reads
DIF files from any version of Lotus 123.
3. Version 2.0 would bomb if any row or column, when added
together, exceeded a -2,147,483,648 or +2,147,483,647.
Version 2.01 will now warn you if this condition exist and
will not allow the keyboard created file to become "active"
until you drop a zero or two from one or more cells. However,
DIF and SYLK imports that exceed this limit can still bomb
the program.
4. Any row label, column label, or data point from a SYLK
or DIF file that exceeds a length of ten characters is now
automatically truncated to a length of ten characters.
5. Version 2.0 had a bug that often-time would dump the program
when run on a Hercules system. Version 2.01 requires Hercules
users to pre-load SIMCGA by using the batch file, HERCGRAF.
By pre-installing SIMCGA, GRAPHER2 will not have its "string
space corrupted".
6. GRAPHER2 will now display graphs in color. The color is
"rotated" so that each display of a graph is in a different
color. (Some color systems will not readily support the display
of color on a 640x200 graphic screen resolution. If this is the
case, your graphs will be displayed in monochrome.)
7. Version 2.01 contains a new procedure for defining the name
of a snapshot file. This procedure will determine the next
available extension number for the snapshot by using a binary
search. This is a tremendous speed improvement in that it will
search 1000 possible numbers and establish the next available
number in under 1/2 second. This change also allows compata-
bility between GRAPHER2 and SLIDESHO.
Registration
------------
Registration of GRAPHER2 automatically is registration of SLIDESHO
and entitles you to free update notification and reduced costs for
all revisions of both.
When you register this program, you will also receive SNIPTABL with
its pre-printed manual. SNIPTABL is a TSR program to snip data for
GRAPHER2 while another program is running. SNIPTABL uses 10,272 bytes
of DOS memory, leaving the rest of DOS free for your other programs
- Note: requires DOS 3.0 or newer.
Registration form is at the end of the manual (GRAPHER2.DOC).
The Future
----------
Future development plans for GRAPHER2 include:
> more graph type options! Line graphs will support negative
as well as, positive data. Line graphs will allow single
columns of data to be charted (like the Column and Pie
Charts do). We also have plans to include Polar Charts and
Horizontal Column Charts, among others.
> a future release of GRAPHER2 will include MACROS! You will
be able to automate all of GRAPHER2's menu options using a
built-in macro language.
> a TSR utility to "snip" displayed graphic images created
by another program while that other program is running and
save them as GRAPHER2 snapshot for use by SLIDESHO.
> a TSR utility to "snip" text screens created by another
program while that other program is running and save them
as a snapshot file (graphics screen) to include into your
slide show(s).
> a utility to convert snapshots (graphic images) into various
other file formats, such as, possibly BSAVE and PIC files.
