- README.TXT 6/12/1991
-
- We hope you will like PENDULUM, and if you do, we hope you will purchase
- your very own, (cheap) registered copy. When you do, you will get the latest
- version of the program, and a printed manual containing much additional
- information and an INSTRUCTOR'S GUIDE. Your name will be added to our
- mailing list, and you will receive notices about upgrades and about other
- educational programs which we plan to develop. Using your registered copy you
- will avoid delays in starting the program and you will no longer be shown the
- initial screens, which encourage unregistered users to buy the program. After
- you receive your registered copy you will have access to our free technical
- support for a period of six months. This support will be provided by mail
- or through Compuserve.
-
- With this program we introduce a novel approach to shareware distribution.
- As with all shareware, we encourage you to make copies and to distribute the
- program as widely as you like. The novel features of our system are the
- following:
-
- 1) You can duplicate and distribute registered or unregistered copies.
- Any copy you make of your registered program will, also be registered
- for your computer but it change to "unregistered",when run on a different
- computer.
-
- 2) When you run an unregistered copy more than once, you will be offered
- ordering information. This information will contain a code for your
- computer, and we will use this code to produce your registered copy.
-
- 3) The Pendulum program uses several text files and it also comes with
- an INSTALL program, with this "README" file, and with some additional
- auxiliary files. To ensure that only complete and unadulterated copies
- are distributed, we require that all these files be present in their
- original form, for the program to run for the first time on any computer.
- For subsequent runs this requirement is relaxed, to let you edit some
- of the "help" files in accordance to your taste, or the needs of your
- students. You should keep one unmodified copy of the original disk, if
- you want to distribute the program for use on other computers.
-
-
- When you receive the disk registered for your computer, be sure not to
- run it on a different computer (at least not before making a copy),
- or you will loose your registration.
-
- To run the program simply put the floppy disk in the disk drive, close the
- door, type a: (assuming that "a" is your floppy drive; or else type b: ) and
- press the "enter" key. (At this point you have, most probably, done all this
- already, since you are obviously reading this message). Then, at the DOS
- prompt type PENDULUM and press the "enter" key.
-
- You can also install the program in any directory of a hard- or floppy-disk
- by copying all the files to that directory or by running the INSTALL
- program. INSTALL can also be used for making copies, and will ensure that
- all the necessary files are present and in good order. (Remember that all the
- files must be the original versions, for the program to initially run on a
- different computer).
-
- Command line options are sometimes useful when running PENDULUM. For example
- type PENDULUM L3B and press "enter" if you want to use a laser printer (L)
- which is connected to the parallel port 3 and in addition you want to enforce
- "black and white" (B) or monochrome display. These choices are retained for
- future runs until you enter another command line option. The defaults are
- LPT1, dot-matrix, and color. Use (D) for dot-matrix and (C) for color.
- The order of the parameters is irrelevant.
