INSTALL.DOC Installation Instructions for PC-CLASS. This file includes
instructions for installing PC-CLASS on your computer, customizing
PC-CLASS to fit your hardware configuration and the way you
expect to use the program, and printing a hard copy of the User's
Manual, PC-CLASS.DOC, on your printer. Copyright (c) 1986 by
Kenneth L Lindsay, Aiga Publications, PO Box 148, Laie, HI 96762.
I. INSTALLING PC-CLASS on Your Computer
A. List of Files on the Distribution Disk.
1. CLASS.COM The main program file, for use on computers WITHOUT
an 8087 floating-point co-processor.
2. CLASS87.COM A separate version of the main program file, for use
on computers WITH an 8087 floating-point co-processor.
3. CLASS.TXT A data file used by the main program as a kernel upon
which to build a class database by adding data for each
student.
4. DEFAULT.STP A file containing setup information for customizing
CLASS to fit the user's particular hardware config-
uration and file structure. User modifiable via
Option 1 of the INSTALL.COM program. See below.
5. COLOR.STP A setup file preconfigured for an 80-column, 66 line
per page printer with one-inch top and bottom margins,
two floppies, and the following color assignments:
Background = Blue Foreground = Lt Yellow
Emphasis = Lt Cyan Box Borders = Lt Magenta
As supplied, DEFAULT.STP and COLOR.STP are identical.
6. MONO.STP A setup file preconfigured for a black and white
monitor, but otherwise identical to COLOR.STP.
Background = Black Foreground = White
Emphasis = Hi Intensity Box Borders = White
7. DEFAULT.CRV A file containing tables for letter-grade/numeric-
grade conversions in either direction when not grading
on a curve, and for numeric-grade to letter-grade
conversion when grading on a curve. The file may be
easily modified by the user via Option 2 of the
INSTALL.COM program. See below.
8. ABCDF.CRV An alternative .CRV file for use with 5 letter grades
(A, B, C, D, and F) instead of the 13 letter grades
used in DEFAULT.CRV (A+, A, A-, ... D+, D, D-, F).
<FF>
9. INSTALL.COM A program for use in creating customized DEFAULT.STP
and DEFAULT.CRV files. This is ordinarily used only
during installation, but it is possible to use it to
create several different .STP and/or .CRV files with
different names, and to select which .STP and .CRV
files to use when loading the PC-CLASS.
See PC-CLASS.DOC for more details.
10. LIST.COM A program to list PC-CLASS.DOC on your printer. LIST may
also be used to list INSTALL.DOC, DEFAULT.CRV, and
DEFAULT.STP if you wish to do so.
11. README.DOC A file giving a brief description of PC-CLASS and
telling how to access the two documentation files.
12. INSTALL.DOC A file giving instructions for installing PC-CLASS.
13. PC-CLASS.DOC The main documentation file, with instructions on how
to use PC-CLASS.
14. PC-CLASS.INV A convenient Invoice form for use in sending your
User-Supported Contribution and describing the system
on which you will be using PC-CLASS.
15. PC-CLASS.BAT A file to load CLASS.COM for the user who tries to run
the program without reading the manual.
B. Additional Files Created by PC-CLASS on the Data Disk.
1. FILELIST.LST A file containing the scan rate for the file selection
screen and a list of the class databases on that disk.
If there are more than 16 databases, only the 16 most
recently created databases are listed. Each database
consists of a set of four files:
2a. DBNAME.TXT The main database file, where DBNAME is a user-created
name; i.e., PSYCH.TXT or SEC4.TXT.
2b. DBNAME.TBK A backup file containing the previous version of
DBNAME.TXT as it existed before being loaded by
PC-CLASS for modification. This provides a means
for recovering from disasters with minimum difficulty.
2c. DBNAME.HDR An auxiliary file containing a header line (at most
64 characters) which will appear as the top line of
each page whenever the database is listed, as well as
names (up to 32 characters for describing each column
of grades in the database.
2d. DBNAME.HBK A backup file containing the previous version of
DBNAME.HDR as it existed before being loaded.
<FF>
C. Disk Storage Requirements.
Disk Storage requirements are about 0.2K per student plus about 3.8K per
class. Thus an entire year's records should fit easily on a single
double-sided floppy disk, and a semester's records could probably
fit on the same disk with the program files on a single-drive system.
The most common arrangement will probably be to place the program disk
in Drive A and a data disk in Drive B; this is the arrangement assumed
in the DEFAULT.STP file. Any desired hard disk arrangement can also
be accommodated easily. There would be no advantage to using a RAM
disk, since PC-CLASS loads the entire database into RAM on startup
and unloads the database to disk only when exiting the program or
switching to a different class database. A print spooler, such as the DOS
PRINT command, will definitely be useful, since PC-CLASS does not have a
built-in spooler. Finally, for those users with an 8087 floating-point
co-processor, a separate version, CLASS87.COM, is provided on the
distribution disk. This takes full advantage of the 8087 and will speed
up calculations considerably, but will have no effect on disk
input/output times.
D. Actual Installation
All of the above information has been provided so that you will be
better prepared to make an informed decision about how best to fit
PC-CLASS into your particular way of using the IBM PC. In particular,
you must decide which drive (and directory, if you have a hard disk)
to use for the program files and which to use for the data files.
Once these decisions have been made, the actual installation is
extremely simple, since PC-CLASS is NOT copy-protected.
1. Formatting a Program Disk and a Data Disk. (This step can be
omitted if you will be installing PC-Class on a hard disk.)
a) Place your DOS system disk in Drive A and a fresh unformatted
disk in Drive B. At the A> prompt, enter: FORMAT B:/S
Then press any key to indicate that the fresh disk is in place.
When formatting is complete, respond N when asked if you want
to format another disk. Remove the formatted disk and label it
PC-CLASS Program Disk (Write the label before placing it on the
disk, or use a felt-tipped pen carefully.)
b) Place another fresh unformatted disk in Drive B (unless you
plan to use the program disk for both program and data, in
which case proceed to step 2). At the A> prompt, enter: FORMAT B:
Proceed as in step (a), but label this disk PC-CLASS Data Disk.
<FF>
2. Transferring Program Files to your Program Disk.
a) Place the PC-CLASS distribution disk in Drive A.
b) Unless you are installing PC-CLASS on a hard disk, place the
freshly formatted PC-CLASS Program Disk in Drive B and at the
A> prompt, enter: B: You should now see the B> prompt.
If you are installing PC-CLASS on a hard disk, log onto the
sub-directory where you plan to install PC-CLASS. (You may have to
create this sub-directory first. If so, follow the directions for
the MKDIR command in the DOS manual.)
c) Enter: COPY A:*.*
d) If you do NOT have an 8087 floating-point co-processor, you may
want to enter: ERASE CLASS87.COM
Similarly, if you DO have an 8087 floating-point co-processor,
you may want to enter: ERASE CLASS.COM
You may also enter: ERASE PC-CLASS.BAT if you wish, since this
file is not likely to be needed if you read the manual and learn
that CLASS, and not PC-CLASS, is the proper way to start PC-CLASS.
e) Now remove the PC-CLASS distribution disk from Drive A, replace
it with the PC-CLASS Program Disk, and enter: A:
(If you have a hard disk, merely remain logged onto the PC-CLASS
program sub-directory.)
II. Customizing PC-CLASS for Your Computer System.
A. The SETUP File.
If you have an 80 column, 66 lines-per-page printer, two floppy disks,
and no hard disk, you will probably be able to use either COLOR.STP
or MONO.STP as your DEFAULT.STP. If you have a color monitor, no action
is necessary, since the distribution DEFAULT.STP is identical with
COLOR.STP. If you have a monochrome monitor, all you have to do is
enter: COPY MONO.STP DEFAULT.STP at the A> prompt.
If you have a hard disk, a wide-carriage 132-column printer (or one
with a line feed different from 6 lines per inch), or if you choose
to keep your database files on the PC-CLASS Program Disk, you will need
to create a new DEFAULT.STP file. You will also want a new DEFAULT.STP if
you have a color monitor, and do not like the preassigned colors in
the COLOR.STP file, or the corresponding monochrome attributes in the
MONO.STP file. To create a new DEFAULT.STP, merely enter: INSTALL
at the A> prompt, choose Option 1, and answer the prompts which appear
on the screen.
<FF>
B. The CURVE File.
The numeric-grade/letter-grade conversion tables in the DEFAULT.CRV
file are those used for the classes my wife teaches at Brigham Young
University Hawaii Campus. They can be easily changed to fit your
personal preferences (or the standards at your school or college, if
any). To make such changes, merely enter: INSTALL at the A> prompt,
choose Option 2, and follow the directions which appear on the screen.
The DEFAULT.CRV file on the distribution disk is designed for 13
different letter grades: A+, A, A- ... D+, D, D-, and F. A separate
file, ABCDF,CRV is also provided for use with only 5 letter grades:
A, B, C, D, and F. If you wish to use this file, merely enter
COPY ABCDF.CRV DEFAULT.CRV at the A> prompt.
NOTE: PC-CLASS is designed so that you may maintain any number of
copies of the .STP and .CRV files, each with a different name, and
select which of these files to use each time you run PC-CLASS. See
PC-CLASS.DOC for more information.
III. Making a Hard Copy of PC-CLASS.DOC on Your Printer.
This is the simplest step in the entire installation procedure, although
perhaps the most time-consuming. All that is required is to turn on your
printer and enter: LIST PC-CLASS.DOC at the A> prompt. Then break for
lunch, unless you are fortunate enough to have a print spooler, since it
will take a while to print. You may also print this file if you wish by
entering: LIST INSTALL.DOC
IV. Copying the Invoice and Submitting your Contribution.
At the A> prompt, make sure your printer is turned on and enter:
LIST PC-CLASS.INV
Please fill out the invoice form, enclose your check, and mail to the
address shown on the form. It will be extremely helpful if you will
take an extra minute to describe your system, particularly if your
computer is an IBM PC compatible. Use the Comment section to describe
any problems you encounter or suggestions for incorporation into
future versions.
