of a row or column.

Differential Equation Solver

INSTALLING AND EXECUTING POLYMATH 3.0.2

HARDWARE REQUIREMENTS
POLYMATH runs on the IBM Personal Computer and most compatibles.  Most
graphics boards are automatically supported.  The minimum application
memory requirement is 540 Kb.  POLYMATH works with PC and MS DOS 3.0
and above.  It can also execute as a DOS application under Windows.  
A variety of drivers are provided for most printers and plotters.
Additionally some standard graphics files are supported.

POLYMATH SOFTWARE
The complete set of POLYMATH application programs with a general selection
menu is available on one 3-1/2 inch 1.44 Mb (high density) floppy.  It is
recommended that a backup disk be made before attempting to install POLYMATH
onto a hard disk or a network.  Installation is available via an INSTALL.EXE
program.

INSTALLATION TO INDIVIDUAL COMPUTERS AND NETWORKS FROM A FLOPPY DISK
POLYMATH executes best when the software is installed on a hard disk or a
network.  There is a utility on the POLYMATH distribution disk which is
called INSTALL.EXE.  Simply put the disk in an appropriate drive.  Type
"install" at the prompt, and press Enter.  Follow the instructions on the
screen to install POLYMATH on the particular Drive and Directory that you
desire.  Note that the default Drive is "C:" and the default Directory is
called "POLYMAT3".  You must indicate if the hard drive is a network server.
If you are installing on a network, you will be prompted for a drive and a
directory in which temporary print files can be placed.

POLYMATH INSTALLATION FROM A CD-ROM
The entire set of POLYMATH application programs can also be easily installed
from a CD-ROM.  Simply execute the INSTALL.EXE from the directory of the  
CD-ROM where the POLYMATH files reside.   Do this by typing "install" at the
prompt, and then press Enter.  (See instructions above for more details.)  

EXECUTING POLYMATH
POLYMATH can be executed by entering "polymath" at the prompt when in the
drive and directory used to store the package.  Advanced users can place the
POLYMATH directory location in the path command.

PRINTING FROM POLYMATH
The various printer, plotter and graphics drivers are provided during 
installation.  If your printer is not listed, please install the standard
printer which it can emulate and make sure that it is in the emulation mode
when printing from POLYMATH.  FOR RAPID PRINTING, IT IS HIGHLY RECOMMENDED 
THAT YOU SELECT MODE 1 - HALF PAGE AND LOW RESOLUTION FOR THE PRINTER OPTIONS
DURING INSTALLATION.  
There are two ways to print from POLYMATH.
	First, most users will use the F7 keypress when available in the programs.
This option sends the printer output as setup during the installation.  THE 
MOST RAPID PRINTING OCCURS WHEN MODE 1 for HALF PAGE AND LOW RESOLUTION ARE 
SELECTED DURING INSTALLATION.  Execution of "printset" (the PRINTSET.EXT file 
is in the POLYMATH directory) allows users to modify their current printer 
selection.  
	Second, some users might desire or need screen complete screen copies.  
This is easily accomplished by executing the DOS "graphics" command BEFORE 
executing POLYMATH.  A Print Screen keypress should give fast screen copies 
if the Print Screen output is compatible with the printer.

CONVERSION OF LIBRARIES FROM PREVIOUS POLYMATH VERSIONS TO POLYMATH 3.0
Copy the cnvlib.exe file to the particular subdirectory where the previous
library was stored.  While in this subdirectory, execution of "cnvlib" (the
CNVLIB.EXE file is in the POLYMATH directory) converts all library entries 
on the particular subdirectory.  Sometimes the conversion will be incomplete
and modest editing will be required.
