| Aight, i just finished my first hangman game. It's not that great yet. For now it runs on homescreen but im updating it to the graph screen soon. I ran into a bug I need help with though. When you type letters, I haven't anyway of telling if that letter was already used. That also goes into conjuction with my other problem. I just have a 0 stored to a variable. IF you get the letter right, then 1 is added to it. Well this is easy to beat if you press a letter thats in the game already four times, so if the word was gain, you could press a 4 times and win. |

| We could help you more if you posted code or, even better, the program itself |

| What do you mean by "already used"? My guess is the user has already guessed that. Is so, you would need to use inString(. |

What I means is this. If the user presses the A key, A is used. He can then re-use A to win or lose, either way. I on't have anyway to combine stringsm so I have this problem. |

combining strings is easy just add them together using "+"

If you get an Error like that, it means there is nothing in the string at first. I'd store a buffer character to the string first.
Here's what you did something like:
:Str1+"A"->Str1
However before that (towards the begining of the program) you need:
:"8->Str1
This 8 is just a buffer character so you can add onto the string. This makes the string offset by one, but that's better than an error...  |

Can you not just initialise an empty string? On a 68K you can just write:
:""->Str1
This is what I did in my hangman program, and works. I've never used a Z80 calc though, so wouldn't know whether this works. |

On a z80 calc one can define a string as
:""→Str1
But when you try to add characters to it, it will give you an error.
You can recall it and it will show up blank, but trying to do stuff as expr( with a blank string can cause a crash or RAM clear. That's why z80 BASIC programmers usually have to define a buffer character. |

Otherwise, search for string concatenation.

Sure,
:Str1+Str2 |

Well two birds with one stone. I finally got my strs to work. Now you can only use a letter once, which means you must find all letters to win.  I'll type up the code soon and post it. Oh and one more thing, the code uses two different strs that have 4 and 5 letter words. You can edit or add onto the ones I post, but pay attention to the math I use in the program. Both strs have the same amount of words. |
