Getch help

[TokenHerbz]

I cant find a good tutorial of getch...
Anyways, i think rather then useing get ans (which will want a number) getch is to take in ANY character correct?

Anyways, if im wrong correct me, otherwise help my understand this...

code:

var answer: int:= 0 proc ans     getch(answer)     if answer = 1 then         exit     end if end ans loop     put "Press 1"     ans end loop put "You did it, thanks"

Yeah i get errors...
Dont laught.. Im horrible at this, meanwhile explaine getchar, and hetch, (or the ones kinda like that)

Please explain there use's, and give me a simple example...

Thank you, and like i said, theres no tut which helped me.

i got it working with letters, but i cant get it to work with numbers...

code:

var leave: boolean := false proc ans     var ch : string (1)     getch (ch)     if ch = 'a' then         leave := true     end if end ans loop     put "Press a"     ans     if leave = true then         exit     end if     cls end loop put "You did it, thanks"

First of all, 'getch' only takes ': string (1)' variables (it's probabily in the F10 area). And so what happens is it "getch's" whatever is pressed, without displaying it.

Here is what you needed your program to do. If you take out the comment, theres no more blinking light (cursor).

Turing:

var answer : string (1) %setscreen ("nocursor") loop     put "Press 1"     getch (answer)     if answer = "1" then         exit     end if end loop put "You did it, thanks"

Now after you figure that out, you can play with it, and make password things, here's an example thatrelates to that last program.

Turing:

var answer : string (1) var total : string := "" setscreen ("nocursor") loop     locate (1, 1)     put "Enter your password"     getch (answer)     if answer = (KEY_ENTER) then         exit     else         total += answer         locate (2, length (total))         put "*"     end if end loop locate (3, 1) put "Password = ", total

ok, but i want to getch numbers...

How can u get a number like getch? so that if i press say A, and it was a proc, i can call it...

or if i press 1, then ill do what ever..., like i sayd, i want to use numbers

[jamonathin]

Read through what I wrote. Getch can ONLY use : string (1), not any integer value. We can play around with our inputed variabled, and change it into an integer, but we cannot GETCH ( var :int ).

If you are "getching" for a number, use quotes around it in you if statement. Just like I did in that previous post.

Here is another sample program. . .

Turing:

var input : string (1) var numb : int loop     cls     put "Enter a Whole Number."     getch (input)     if strintok (input) then         numb := strint (input)         exit     else         put "'", input, "' is CLEARLY not a whole number."         delay (1250)     end if     % Or     %exit when strintok (input) end loop %numb := strint(input) put "Thank You. Your number is ", numb, "."

I wouldn't expect you to understand the code that Jamonathin just posted (the type conversion parts) so, if you wish, you may learn about them in the String Manipulation Tutorial. (It's the second section.)

Thank you.
