They were designed to run on an IBM-PC with color graphics and were created with DOS 2.1 or later versions. No efforts have been made to make the disks compatible for use with other computers but several computers can be used. Many of the programs have been run on computers with monochrome monitor. Color contrast may be a problem (which is corrected by changing a few statements) and in a few places the "SCREEN" and other commands causes difficulties, but these can be revised to meet the characteristics of individual machines.

Please read the "Limited Use License Agreement" before opening the sealed disk package which contains the licensed programs. Opening the disk package indicates the reader's acceptance of the terms and conditions of the Agreement.

Diskette Care

1. Keep the disks away from heat.
2. Keep the disks away from magnetic and electric fields
3. Keep them dry.
4. Keep them away from dust.
5. Remove them from the computer before turning it off.

Backing up the Capper Diskettes
It is smart to make backups and keep them in a safe place that is different from where you keep the original diskettes. Here are the steps to do so. For these steps we are going to assume that your 3.5-inch disk drive is drive A. If your 3.5-inch disk drive is drive B:, substitute a B: whenever you see an A:.

1. Boot your computer in the normal fashion.
2. Make sure you are at the C: prompt, some computers may place you into Windows during the computer's startup procedure.
3. Duplicate the first Capper diskette with diskcopy. DISKCOPY A: A:
4. When prompted for the SOURCE, insert the original Capper diskette into drive A: and press Enter.
5. When prompted for the TARGET, insert a black diskette into drive A: and press Enter. Warning, if the diskette is not blank, any information on it will be destroyed.
6. Depending on the DOS version you are running, you may be prompted multiple times for each disk.
7. If prompted for another copy of the same diskette, answer no.
8. If prompted to duplicate another diskette, answer yes so that you may duplicate the remaining 2 diskettes. Otherwise, repeat steps 3 through 6 for each of the two remaining diskettes.

Installation of the Capper Diskettes

For this installation procedure we are going to assume that your 3.5-inch disk drive is drive A:. If your 3.5-inch disk drive is drive B:, substitute a B: whenever you see an A:. Also, we are going to assume that your hard drive is C:. If your hard drive is D:, substitute a D: whenever you see a C:. There are three diskettes to the Capper system, perform the following steps to install them onto your hard drive.

1. Boot your computer in the normal fashion.
2. Make sure you are at the C: prompt, some computers may place you into Windows during the computer's startup procedure.
3. Make sure you are in the root directory of the C: drive. CD/
4. Make a CAPPER directory. MD CAPPER
5. Change into the newly created directory. CD CAPPER
6. Put the first Capper diskette into the A: drive.
7. Copy all the files from the Capper diskette onto the hard drive. COPY A:/*.*
8. Repeat steps 6 and 7 for the remaining two diskettes.
9. Create a batch file to run the Capper system. COPY CON CAPPER.BAT
10. Type the line that will redirect all calls to the floppy drives to the hard drive. ASSIGN A=C B=C
11. You can run the Capper system with one of three different BASIC environments, BASICA, GWBASIC, and QBASIC.

    Type one of the following lines, depending on which environment you
    have installed on you computer.
    BASICA CAP02
    GWBASIC CAP02
    QBASIC /RUN CAP02

12. Type the line that will undo the floppy drive redirection. ASSIGN
13. Close and write CAPPER.BAT to the hard drive. Ctrl+Z or F6

Running the Capper System

To run the Capper system, type CAPPER at the C: prompt while in the CAPPER director.

The program present a menu. You may select from it. Usually you will be sent to a more detailed menu. A menu is a list of computer programs or files on the hard drive. You select the number you want, enter it, the system finds it, and loads it into its working space. You do the rest.

There are 2 ways the system takes in numbers and letters. These may be confusing at first. You may be asked to tap a key. You may do so and nothing happens. You need to tap the ENTER key or broken arrow key at mid-right center of the keyboard. Otherwise action usually takes place on the screen.

If you are ever stuck and you do not know what to do next, hit Ctrl and Break, then type RUN. This will run the program presently available. If still "stuck", type RUN "CAPPER." This will take you to the menu and you can start again.

If you are in a program and have made mistakes, etc., and do not want to continue, hit Ctrl (left) and Break. This stops the program. To start from the beginning, just tap F2. To start at some line in a program, e.g., 1213, type RUN 1213.

If you ever want to see the code (perhaps to look at an equation) hit Ctrl and Break, then the F1 key. This automatically types LIST. Then tap ENTER. This will list the entire program.

You can list 10 lines after some line, say line 1200, by entering LIST 1200-1 300.

To print what shows up on a screen (if you have a printer) start the program, then hit Ctrl and PrtSc and continue using the program. Printer-computer relations are very complex. I have avoided printing throughout. Graphs can only be printed on some machines. For public display, I have found 2x2 slides of the monitor effective and inexpensive (relative to other display hardware now available).

The programs are designed to expand and clarify topics in the text. They allow reader and student to explore relationships, to test their understanding, and, very importantly, they can become working tools for the natural resource manager. In some cases, a first-time user will have data ... but usually not. It is best to try to make realistic use of the programs and not to be frustrated with not having data. Hypothetical situations can be created or imagined, then the program can be run and evaluated for later use - either to master a concept, note a new relationship, or decide whether it can be used when data become available. In most cases representative values are suggested. Deviating very far from these may cause the program to exceed reasonable limits. If this occurs, re-run the program. Checks for errors and mis-typed entries have not been built into many of the programs because of costs and the space required to do so.

The contents of the Capper disks are listed on the following pages. They may be called into action by normal procedures by using Run "Q:CAPXXX" where Q is the letter of your disk drive or where the file is stored and XXX is the additional number or letters of the file name.
