I mean I was not trying to make fun, but there is some serious thinking out of the box to be done with this program (he could have).

What that code needs is rewriting from scratch. With that in mind, here's code I still wouldn't consider a good hangman game because, for one, there's no picture of a hangman and no other indication of how close you are to losing.

:"ABCDEFGHIJKLMNOPQRSTUVWXYZ→Str0

:Repeat length(Str1)<33
:ClrHome
:Disp "WORD? (32 CHARS)"
:Input "",Str1
:End

:"space→Str2
:For(I,1,length(Str1
:sub(Str1,I,1
:If inString(Str0,Ans:"-
:Str2+Ans→Str2
:End
:Ans+" →Str2
:"space"+Str1+"space→Str1

:DelVar TRepeat Str1=Str2 or T=12 edit for difficulty
:Output(1,1,Str2

:Repeat 30<Ans and Ans<94
:getKey
:If Ans=45:Goto Q
:End
:Ans-20-5int(.1Ans)-2(Ans>45→K
:sub(Str0,Ans,1→Str3
:Output(4+(K>16),17fPart(K/17,Ans

:inString(Str1,Ans→I
:T+not(Ans→T
:While I
:sub(Str2,1,Ans-1)+Str3+sub(Str2,Ans+1,length(Str2)-Ans→Str2
:inString(Str1,Str3,I+1→I
:End

:End

:Lbl Q
:ClrHome
:"YOU "+sub("WIN!!LOSE!",6-5(Str1=Str2),5

Maybe what you could do is tie the number of tries to the length of the word. So, if the word is apples, then you would get six chances to guess it. Does that work any better?

P.S. I believe the Str0 in :Repeat length(Str0)<=32 is supposed to be Str1.

But it's harder to guess a short word than a long one! If the word (or phrase) is long, that makes it more likely that any given letter will actually be in it, and you're also more likely to recognize the word early on.

Fixed. Also stopped the number of guesses from going down even if you guess correctly - this shouldn't happen in hangman.

Is going to error if Ans<1 or Ans>27, might add in repeat.

If you're going to add error checking for that, you should add error checking for when the user inputs the word at the beginning. Right now, the user could have a word consisting of a command or theta or whatever. Personally, I would just leave off error checking. I think the code looks more elegant that way.

Anyways, I added the error checking for both of those things, I think it doesn't look that bad. Actually, this way any non-uppercase-letter token is treated the same as a space, and entering "sin(THETA)" as the word will have the other person guessing "sin(-----)".

When I tried out the program, I saw a few changes that you can make:

  • :Repeat length(Str1)<33
    can be
    :Repeat 33>length(Str1


  • :" →Str2
    :For(I,1,length(Str1
    :sub(Str1,I,1
    :If inString(Str0,Ans:"-
    :Str2+Ans→Str2
    :End
    :Ans+" →Str2
    :"space"+Str1+"space→Str1
    can be
    :"?
    :For(I,1,length(Str1
    :If inString(Str0,sub(Str1,I,1
    :Ans+"-
    :End
    :sub(Ans,2,length(Ans)-1→Str2


  • :DelVar TRepeat Str1=Str2 or T=12
    can be
    12→T:While Str1≠Str2 and T


  • :Output(4+(K>16),17fPart(K/17,Ans
    needs to be
    :Output(4+(K>16),round(17fPart(K/17)),Ans


  • :sub(Str2,1,Ans-1)+Str3+sub(Str2,Ans+1,length(Str2)-Ans→Str2
    needs to be
    :sub(sub(" "+Str2,1,I-1)+Str3+sub(Str2+" ",I+1,length(Str2)-I+1),2,length(Str2)→Str2


  • :"YOU "+sub("WIN!!LOSE!",6-5(Str1=Str2),5
    can be
    :"YOU "+sub("WIN! LOSE!",1+5not(T),5

The one other change I would make is to add a ClrHome before the main game loop,
because it looks kind of sloppy to just write over the "WORD? (32 CHARS)" text.

Darn. In that case, how about K-16(K>16)?

So, here's what the program looks like right now:

:"ABCDEFGHIJKLMNOPQRSTUVWXYZ→Str0
:{6.9,6.7,5.8,4.9,4.7,4.8,3.8→L1
:Repeat 33>length(Str1
:ClrHome
:Disp "WORD? (32 CHARS)"
:Input "",Str1
:End
:"space
:For(I,1,length(Str1
:If inString(Str0,sub(Str1,I,1
:Ans+"-
:End
:sub(Ans,2,length(Ans)-1→Str2
:dim(L1→T
:ClrHome
:While Str1≠Str2 and T
:Output(1,1,Str2
:Repeat 30<Ans and Ans<94
:getKey
:End
:If Ans=45:Goto Q
:Ans-20-5int(.1Ans)-2(Ans>45→K
:sub(Str0,Ans,1→Str3
:Output(7+(K>14),K+1-13(K>14),Ans
:inString(Str1,Ans→I
:If I:Then
:While I
:sub(sub(" "+Str2,1,I-1)+Str3+sub(Str2+" ",I+1,length(Str2)-I+1),2,length(Str2)→Str2
:inString(Str1,Str3,I+1→I
:End
:Else
:Output(iPart(L1(T)),10fPart(L1(T)),sub("^^I--IO",T,1
:T-1→T
:End
:End
:Lbl Q
:Pause "YOU "+sub("LOSE!WIN! ",1+5(Str1=Str2),5
:ClrHome

A few more improvements. Also, one of your optimizations (in the initialize-Str2 loop) I just realized doesn't actually work when the word to be guessed is actually a phrase.
:"ABCDEFGHIJKLMNOPQRSTUVWXYZ→Str0
:Repeat 33>length(Str1
:ClrHome
:Disp "WORD? (32 CHARS)
:Input "",Str1
:End
:"?→Str2
:For(I,1,length(Str1
:sub(Str1,I,1
:If inString(Str0,Ans:"-
:Str2+Ans→Str2
:End
:sub(Ans,2,length(Ans)-1→Str2
:8→T
:ClrHome
:While Str1≠Str2 and T
:Output(1,1,Str2
:.1{69,67,58,49,47,48,38,38
:Output(iPart(Ans(T)),10fPart(Ans(T)),sub("^^I--IO ",T,1
:Repeat 30<Ans and Ans<94
:getKey
:End
:If Ans=45:Goto Q
:Ans-20-5int(.1Ans)-2(Ans>45→K
:sub(Str0,Ans,1→Str3
:Output(7+(K>14),K+1-13(K>14),Ans
:inString(Str1,Ans→I
:T-not(Ans→T
:While I
:sub(sub(" "+Str2,1,I)+Str3+sub(Str2+" ",I+1,length(Str2)-I+1),2,length(Str2)→Str2
:inString(Str1,Str3,I+1→I
:End
:End
:Lbl Q
:Pause "YOU "+sub("LOSE!WIN! ",1+5(Str1=Str2),5
:ClrHome

The calculator should crash on this line:

:sub(sub(" "+Str2,1,I-1)+Str3+sub(Str2+" ",I+1,length(Str2)-I+1),2,length(Str2)→Str2

When I copied the program from my calculator to the post, I somehow added a -1 to the second sub( command. The correct line is:

:sub(sub(" "+Str2,1,I)+Str3+sub(Str2+" ",I+1,length(Str2)-I+1),2,length(Str2)→Str2

Sorry about the mistake.

The program looks pretty optimized to me. Who wants to come up with the next program?

Ok, so the final tally
Original: 2,442 bytes
New:444 bytes
Saved:1998 bytes
New program is 18.2% of what it was

here it is: [attachment=1892:attachment]

[edit] okay, okay, it's 444 instead of 44, but doesn't cutting a 2,442 byte program to 44 bytes look good?

I think you mean the new program is 444 bytes. I guess we can move on to the next program then.

EDIT: I like the idea of seeing the before and after in terms of program size, so here are the results for the Frogger program:

Original: 1,622 bytes
New: 807 bytes
Saved: 815 bytes (50.2% of program removed)

For the next program, I decided to go with a game that uses the graph screen rather than the home screen. Don't worry, though, the code is still pretty crappy :D

We need to maintain the credits, I'm guessing? Or are we allowed to remove it since JacKaL software wouldn't recognize the final product at all?
I actually removed the credits from the Frogger game, since it really just obstructs the gameplay and doesn't add anything. Likewise, the Football game isn't enhanced by the credits.

So, we can get rid of this code right from the get go:

:Output(4,2,"D. JacKaL")
:Output(5,7," SOFTWARE")
:Output(1,1,"****************"
:Output(8,1,"****PRESENTS****"
:Pause
:ClrHome
:Output(1,1,"****************
:Output(8,1,"****************
:Output(4,1,"A GAME PORTED BYKAIVAN KHOSHROO
:Pause :ClrHome

I've been working on optimizing the Football game tonight, and one of the things I noticed is that the author really likes to jump out of his For( loops with branching. For example, you see several of these code snippets throughout the program:

:For(C,61,32,-1
:Pxl-Change(C,47
:getKey→K
:If K=105:Goto 2:End
:Lbl 2

I'm sure the author probably thought a For( loop worked best because it has the built-in variable declaration and construction, but it really doesn't work very well in this situation. So, I decided to replace the For( loop with a Repeat loop:

:61→C:1→K
:Repeat getKey=105
:K(C≥32 and C≤61)+(C=32)-(C=61→K
:C+Ans→C
:Pxl-Change(Ans,47
:End

I was wondering if anybody else has a better solution, or if this is the best way to go?

What about If K=105:32→C ?
