GRADE GUIDE V4.19 is distributed on two archived files

           GRGID4A.EXE    and    GRGID4B.EXE

Each of these files will fit on a 5¬ inch 360 kilobyte disk.
A third file, INSTALL.EXE, contains a program which will read the
other two files and use them to create the files you will need to
run the GRADE GUIDE program.  Sometimes all three of these files
are grouped together in one large file called GRGID419.ZIP.  To
configure the program to run on your computer, run the INSTALL
program while the INSTALL.EXE and GRGID4A.EXE files are in your
default directory (for example, on your A: drive).  The INSTALL
program will properly install GRADE GUIDE for you onto a hard
disk or one or more floppy disks.
