___
This is the code for the computer in Mercy, since a lot of interest
has been shown in its mechanics. Note that these are code snippets
and not a library file; hence the lack of exclamation points in
this file.

First, some simple grammar lines:
___

verb "log"
			* "in"								 -> Login
			* "into" noun						 -> Login;
			
verb "login"
			*									 -> Login;

[ LoginSub;
  "[That verb doesn't make sense in this context.]";
];

verb "use"
			* noun								 -> Use;

[ UseSub;
  "[Be more specific; how do you want to use that?]";
];

___
I decided to put in a line for 'use' since "I'm using the computer" is
a pretty common way to say that you're operating a computer. It also
puts in a nice message for Scott Adams graduates who want to 'use
blade'.

Then, some constants to keep it simple to remember what colors correspond to
which numbers (in case you've got an interpreter that doesn't support colors,
the computer screen itself is shown in white-on-red).
___

constant white  9;						! for screen effects
constant black  2;
constant red    3;

___
The following routines are the meat of the computer; you can look up
the various assembly opcodes in the Z-Code Specs, which are highly-
recommended reading.
___

! WaitForKey waits for a key to be pressed.

[ WaitForKey notNeeded;
  @read_char 1 notNeeded;
  rtrue;

! LowerComment works in conjunction with PCscreen. It prints a line of text
! on the lower window.

! PCscreen prints out the display that the player sees when using the
! computer.

Finally, the code for the computer object itself. Note that I decided that sitting down
in the chair would indicate that you want to use the computer; perhaps an unfair
assumption I'll change in release 2.
___

object -> pc "computer"
	with name "pc" "computer",
	initial
	"An abused computer sits in the corner. It's a crummy 386, but it came 
	free with the place. Someone's left it on, which is sloppy.",
	description
	"The screen displays the login screen, which is bathed in red text graphics.
	 Sometimes well enough should be left alone.",
	before
	[;     take:  "You don't want to; besides, it's bolted to the table.";
	   switchOn:  "It's already on.";
	  switchOff:  "What for? Really, it doesn't matter. It looks sloppy, but so
	               what? Life just is too long. Why clean up after yourself? There
	               isn't anything left. Just leave things as they are.^^And besides,
