                              Version  5.1
                               24 Jan 92


Welcome to STATGRAPHICS!  This is the READ.ME file for Version 5.1.  It
contains supplementary documentation and last-minute release notes.


A.  Distribution Files

    1.  Most files are distributed in compressed form, with file extension
"ZIP".  These are normally expanded during the Installation procedure.  An
exception is the file HELPLINE.EXE on the disk containing Graphics Drivers 2.
This file contains a compressed collection of diagnostic utility programs that
may be useful for troubleshooting if you ever need to call the HelpLine.  This
file is "self-extracting", so to obtain the individual expanded programs in
the default directory on your hard disk, simply enter:

     HELPLINE          (if HELPLINE.EXE was copied to your hard disk)

or

     A:HELPLINE        (otherwise)


B.  Software Behavior

    1.  **** VERY IMPORTANT ****  If you are upgrading your copy of STATGRAPHICS
from Version 4.x and have existing macros and hot keys, then you will need to 
run a provided conversion utility program supplied with the system.  (This is 
due to a necessary change in the way STATGRAPHICS handles international 
characters.)  The utility is part of the HELPLINE.EXE file (described above).
Run HELPLINE to unload the utility programs onto your hard disk.  Then enter the
following command from your STATGRAPHICS system directory (STATG):  

     ADDON 6

A few moments later, you will see a message about a new procedure being added to
STATGRAPHICS.  To run the new procedure, start STATGRAPHICS, press F8 at the 
Main Menu, and enter the command CONVERT.  Then follow the instructions provided
in the pop-up window that will appear.

    2.  If you select a PostScript printer during Installation, you will find
that your STATGRAF.BAT startup file contains lines like:

     SGPOST  X=6.0  B=...
     SGRAFEXE  ...  P10 ...
     SGPOST  R

The SGPOST and the P10 references permit text screen shots to be sent to the
PostScript printer, but do not affect graphics output.  If you have also
selected a second printer, you will not be able to direct screen shots to the
second printer unless you remove the two "SGPOST" lines and the "P10"
reference from the "SGRAFEXE" line.  After their removal, you will still be
able to get graphics output on the PostScript printer.

    3.  STATGRAPHICS should run properly as a full-screen application under
Windows 3.0.  However, if you take the approach of calling STATGRAPHICS from a
PIF file, the system may unexpectedly pause for a keystroke entry while
running.  You can prevent this apparent "hang" by changing the Execution Mode
option to EXCLUSIVE.  No other changes from the defaults are required, but the
following non-default options can improve performance:
 
  KB required:  400          Foreground priority:  1000  (an advanced option)

Also note that there is a STATGRAPHICS icon for Windows available:  it is the 
file SG_WIN.ICO stored within the HELPLINE.EXE utility collection.  (See A.1.
above.)

Windows users should also see additional important information in the Windows
Appendix in the Installation Guide.  The information above supersedes the PIF
file restriction noted in the printed documentation.


C.  Documentation Addenda

    1.  If you select the "High Resolution EGA" graphics display option, the
default screen resolution depends on your particular hardware, as follows:

  800x600 -- Genoa Super EGA, Tecmar EGA Master 800, Video7 Vega VGA
  800x560 -- ATI VIP, ATI EGA Wonder
  640x480 -- Paradise AutoSwitch EGA 480, Quadram ProSync, Video7 Vega Deluxe
  640x350 -- other Enhanced Color Displays (ECDs)
  640x200 -- other Color Graphics Adapters (CGAs)

    2.  If you select the "High Resolution VGA" graphics display option, the
default screen resolution is 640x480, but you can increase this for some hard-
ware by using the DOS SET command before starting STATGRAPHICS, as follows:

  SET VGA=800,600,29h -- EIZO Professional MD-B10, newer Orchid Designer VGA,
                         STB Systems VGA Extra
  SET VGA=800,600,54h -- ATI VGA Wonder
  SET VGA=800,600,58h -- EIZO Professional MD-B07, Paradise VGA Professional
  SET VGA=800,600,5bh -- Trident TVGA
  SET VGA=800,600,79h -- Genoa Super VGA HiRes-10 (BIOS Version 2.0 or later)
  SET VGA=640,480,12h -- all VGAs (default 640x480 resolution)

    3.  If you are using an HP PaintJet Printer with an EGA or VGA display,
you may want to use the Color Palette Selection (COLORBAR procedure) to set
graphics screen colors to match the colors used by the printer.  Here are
suggested intensity values, for either a white or a black screen background:

             --White Background--       --Black Background--
  Color       Red   Green    Blue        Red   Green    Blue
    0        1000    1000    1000          0       0       0

    8         150     150     150        400     400     400

   13         100      50      50        800     800     800
   14         100     600     850        100     700    1000
   15        1000       0     540       1000       0     600


D.  Helpful Hints

    1.  The latest version of the GSS*CGI drivers (2.16 in most cases) is
included with this release, so previous STATGRAPHICS users should be sure to
update their drivers during the installation step.

    2.  If you are an APL*PLUS PC System user and want to run STATGRAPHICS
after starting APL, be sure to start APL with an H=1024 parameter.  Also
remember to run DRIVERS.EXE before you start APL.

    3.  If you receive unexpected error messages while trying to start or run
STATGRAPHICS, be sure that your disk is not full.  If it is, there is a slight
chance that some required files were not copied to the disk as the compressed
files were expanded, although the Installation procedure usually detects such
a condition.  If your disk fills during installation, you will need to make
more room and re-install.

    4.  See the Installation Guide for a discussion about how STATGRAPHICS
uses DOS memory (RAM).

    5.  In Version 5, any data files beginning with "STAT" are invisible to
F7, the FILE command, and the File Operations menu choice.  Please rename any
such files in DOS before starting STATGRAPHICS.

    6.  In case of difficulties installing or running STATGRAPHICS, be sure to
see the "Troubleshooting STATGRAPHICS" Appendix in the User Manual.  In
addition, the STSC InfoLine is available 24 hours per day.  It is a telephone
number that anyone can call to get answers to some of the most commonly-asked
HelpLine questions.  Simply dial (301) 984-LINE (984-5463).


Now you are ready to use STATGRAPHICS.  Simply create a new subdirectory for
Version 5, copy the Installation Programs Disk into it, and run INSTALL.
