This program is both available in XTDFPC as in the FPC demoes.
Copyright (C) 1999 by Marco van de Voort
FPCTris implements a simple Crt driven Tetrisish game to demonstrate the
Crt unit. (KeyPressed, ReadKey, GotoXY, Delay,TextColor,TextBackground)
Quality games cost money, so that's why this one is free.
See the file COPYING.FPC, included in this distribution,
for details about the copyright.

{$LONGSTRINGS OFF}
{ Trying to make a tetris from zero as a demo for FPC.
Problems: - Colorsupport is a hack which handicaps creating a better
update mechanism. (is done now)
- Graph version input command has no cursor.
- Graph or text isn't decided runtime, but compilertime.
- Linux status graph version unknown at this moment.
- Graphic and textmode speed of the game is not the same.
The delay is fixed, and the time required to update is
not constant due to optimisations.
Coordinate system:
0 -> TheWidth-1 A figure is coded in a LONGINT like this:
---------
0 | * | ..*. 00100000 MSB
| | ** | ..*. 00100000
V | * | .**. 01100000
| | .... 00000000 LSB
|+ ++ ++|
|++ ++++++| so 00100000001000000110000000000000b
|+++++++++|
---------
