- don't care at all, then I would be happy to to hear from you. Please share
- unmodified copies of this adventure with everyone you meet.

- If you wish to distribute a modified version of this program, please keep my
- copyright intact, indicate that changes were made in the program and in the
- documentation, and list the changes made in the documentation. And if
- possible please notify me of the changes, since I would like to keep track of
- all the different versions.

-
- Scenario:
- ---------
- You have reached the final part of your mission. You have gained access to
- the complex, and all but the last procedure has been performed. Now comes a
- time of waiting, in which you must search for the hidden 12-word message that
- will aid you at the final step. But what choice will you make when that time
- comes?
-
- The scenario for the adventure is meant to be vague. Once the adventure has
- been completed, the scenario will hopefully become clear.
-
-
- Instructions:
- -------------
- This adventure recognizes the standard commands for moving (N,E,S,W), taking
- inventory (I), maninpulating objects (GET, DROP, LOOK), and saving games
- (SAVE, LOAD), as well as many others. Use 2-word 'verb noun' commands, such
- as 'use stack' or 'get all'. Only the first four letters of each word are
- significant. The adventure recognizes about 200 words, so if one word doesn't
- work, try another.
-
-
- Notes:
- ------
- The "stack" is an acroynym for Space Time Activated Continuum Key. You will
- find this object very useful. Try the command "use stack".
-
- This adventure is abstract and a bit on the technical side. Basic knowledge
- of the names of interesting mathematical objects would be a definite asset in
- solving the puzzles. However, detail knowledge of the technical background is
- not necessary, although it will make the adventure more enjoyable and reduce
- the amount of comments of the form "Was that suppose to be funny or what? I
- don't get it"
-
- There is no carry limit, no death traps, and over 200 words in the program's
- vocabulary, so you can hopefully concentrate on solving the adventure instead
- of solving the program. The map of the adventure can be draw on a grid. All
- it takes is a little experimenting to put all the subsets of locations
- together "logically".
-
-
- Compiling Notes:
- ----------------
- There are several source files for the adventure:
- ADV-DEF.H : main adventure data types
- PARSER.C,H : command parser
- TESS-DEF.C,H : adventure world and vocabulary definition
- TESS.C : main adventure file
-
- The adventure can be compiled using Turbo C 1.5. This will result in the
- adventure using a split-screen format for the display.
-
- Compiling with the "tty" symbol defined (-Dtty) will result in a scrolling,
- non-IBM dependent display that should work with most compilers and terminals.
- This can be done by uncommenting the line "TTY=-Dtty" in the makefile.
-
- The following are some of the "non-classical" C features used:
- enum
- functional prototyping
-
- In the function "intro", some compiler may give a warning about the variable
- "k" being used before it's defined. This is intentionally done as part of
- the routine to reseed the random number generator. The srand() routine
- along with the time() could have been used, but they add another 1-2K of code.

- Tesseract Version 2.0 is my first MS-DOS adventure and an exercise in learning
- C. Since this is a direct port of the old BASIC version, it may be smaller
- than some other adventures, and some of the coding might not be too clean.
- For the C version, appropriate changes were made to the data structures,
- additions and small changes made to some of the puzzles, and the ending
- expanded. This version was posted to USENET.
-
- Version 2.01 fixed a few bugs, notably the illegal pointer dereferencing
- when the probability prompt didn't get a decimal point in the input.
-
- Version 2.02 reworded the probabilty puzzle so that it's more "logical",
- and removed the intro screen at the end so that you can quit without leaving
- a tell-tale sign of game playing!
-
- Version 2.03 had some minor clean-up done, an extra hint added to the field
- puzzle, and the "look" command will finally print out the current room
- (relevant only to the tty version). This version was sent to CUG.
-
- The very first adventure that I wrote was in 1982, titled "Hall of the
- Mountain King" (find the Crystal of Light). Tesseract Version 1.0 was the
- second of the three TRS-80 BASIC adventures that I wrote in a two month
- adventure-frenzy during the summer of 1983. The first was "Project Triad"
- (defuse the bomb on the space station), and the third was "Codename Intrepid"
- (deliver a package to another agent).

- ----------
- This is not the usual way you see tesseracts drawn, with two cubes sharing an
- edge. But with the limitations of small ASCII characters, this was the best
- that I could do.
