DOCUMENTATION for THESEUS.PAS

Author:  John E. Ohlson, Jr.

Purpose:  Theseus is an adaptation for Turbo Pascal of a program presented
	  in Paul A. Sand's book, "Advanced Pascal Programming Techniques."
	  It basic purpose is to demonstrate the use of recursive procedures.

	  Theseus first creates a maze ( a different, random maze each time
	  the program is run) and then solves it.  Thus, it does nothing par-
	  ticularly useful, but it is fun to watch.  More importantly, study-
	  ing the code should be most instructive.

Changes to make in the code:
	  Theseus assumes an 80 by 24 screen and creates a 78 by 20 maze.
	  You may change the constants at the beginning of the program if
	  these are not suitable values.

	  The constant wall_chr is ideally a solid block (on my terminal,
	  the hex code 7F creates one).  Substitute the appropriate code for
	  your terminal.  If all else fails, you can use 'X'.

	  The values for up through right in PROCEDURE crt must be changed
	  to the values used by your terminal for cursor control.

	  Finally, the various delays can be adjusted to taste.
