11 ! This Zen simulation is based on the C version v1600003.248b
12 ! by Leonard Richardson (C) 1997, 2000.
13 ! Written originally for the Nerth Pork robotfindskitten contest.
14 ! Reimplemented in Inform by David Griffith (C) 2002.
16 ! Lots more information on robotfindskitten is available at
17 ! http://www.robotfindskitten.org.
20 ! In this game, you are Robot (#). Your job is to find Kitten. This
21 ! task is complicated by the existance of various things which are not
22 ! kitten. Robot must touch items to determine if they are Kitten or
23 ! not. Move Robot with the cursor keys, the numeric keypad, or
24 ! using the vi/rogue movement keys. The game ends when robotfindskitten.
25 ! Alternatively, you may end the game by hitting the Esc or Q keys.
27 ! Developed with Inform 6.21.4 as installed from NetBSD's pkgsrc tree
32 ! 1) More than half of the code is taken up by non kitten items
33 ! (NKIs). When I compiled the code with just five messages and
34 ! no debugging code, the resulting binary was less than 10k bytes.
36 ! 2) If it wasn't already abundantly obvious, this program won't
37 ! compile to Glulx because of copious use of Z-machine assembly
40 ! 3) Compiling for V5 or higher is required due to "style" calls.
41 ! Is there a reason why someone would want to compile this for V4

366 1) I still don't know why already_seen_xy() occasionally causes Robot to
367 get placed on top of another object when a game is started. Fortunately
368 this seems to happen only very rarely and typically only if the
369 difficulty is set to more than 200. This bug also seems to very
370 occasionally put Kitten underneath an NKI.^
372 2) Under earlier versions of Windows Frotz, Robot used to appear as a
373 solid block. This was because of a bug in Windows Frotz which
374 incorrectly makes the cursor opaque. The cursor is now moved off to
375 the upper-right corner so that the game looks okay on terminals that use
376 something other than reverse for the cursor. I still can't figure out
377 how to make Inform hide the cursor completely. At least on xterm and
378 NetBSD's console, @@64set_cursor -1 doesn't work.^
380 3) Under Windows Frotz, an annoying [MORE] prompt might appear at the
381 main menu. This is another bug in Windows Frotz which causes the
382 interpreter to follow Windows' suggestion that something less than 24 or

423 Day and night I feverishly worked upon the machine, creating both a soul
424 which could desire its goal, and a body with which it could realize
425 it. Many who saw my creation called it an abomination, and denied me
426 grant money. But they could not dissuade me from my impossible
427 task. It was a spectre that tormented me always, a ghost I had to give
428 a form and a life, lest it consume me from the inside. And when at last
429 my task was done, when the grey box on wheels was complete and when it,
430 as well as I, knew what had to be done, I felt deep sympathy for the
431 machine. For I had not destroyed the phantom, but merely exorcized it
432 into another body. The robot knew not why this task had to be
433 performed, for I could not imbue it with knowledge I did not myself
434 posess. And at the same time, I felt a sweeping sense of relief sweep
435 over me, that somehow, the dream that had driven me for my entire life
436 had come one step closer to fruition.^
438 ~Gort, Klaatu Verada Nikto~^
440 As I vocally activated the robot, I realized that it was following my
441 instructions, but not out of any desire to obey me. Had I remained
442 silent, it would have performed exactly the same operations. We were
443 two beings controlled by the same force now. And yet, seeking vainly to
444 hold some illusion of control over the machine I thought I had created,
445 I gave my final command.^
447 ~GO!~ I told the box as it began to roll out of my workshop into the
448 frozen desert beyond. ~FIND KITTEN!~^
