Using parameters -- Infinite Loops

[ToTNuim]

For some reason, my code does not accept the parameters (20, 200) or any parameter that's not (negative, positive) and will go into a infinite loop.
Please help!
I just started computer science and I don't know how to "look for problems" in codes!

Turing:

function getInteger (low, high : int) : int     const ENTER : char := chr (10)        var ch : string (1) := 'x'            var number : int := 0     var digits : int := 0     var Negative : boolean := false     put "Please enter an Integer between ", low, " and ", high, " : " ..     loop         loop             if hasch then                 getch (ch)                 if ch >= '0' and ch <= '9' then                     number := number * 10 + strint (ch)                     digits := digits + 1                     put ch ..                 elsif ch = '-' and digits = 0 then                     Negative := true                     digits := digits + 1                     put ch ..                 elsif ch not= ENTER then                     digits := 0                     number := 0                     cls                     put "** This is not a integer **"                     put "Please enter an Integer: " ..                 end if             end if             exit when number >= low and number <= high             digits := 0             number := 0             Negative := false             cls             put "** This number is not between ", low, " and ", high, " **"             put "Please re-enter: " ..         end loop         exit when ch = chr (10) or digits >= 9 and number >= low and number <= high     end loop     if Negative then         result number * -1     else         result number     end if end getInteger % Test Main var num : int var win : int win := Window.Open ("screen:10;70,cursor,echo") num := getInteger (20, 200) put "" put "You entered ", num, " as your number"

Please specify what version of Turing you are using
Turing 4.1.1

Is that big loop just reading a number?

You can already do that:

Turing:

var number: int get number

You don't need hasch. A simple get statement is what you need. hasch only works if there is input. If not, the program will skip over that part, without stopping. That could be the problem.

Also like DtY says, you already have a get statement. Why replicate it? (Which is what you are doing)

[ToTNuim]

Yeah, a "get" statement works
But, the assignment was that I use this code and add "parameters" to it.
Anymore suggestions?

[TheGuardian001]

What initial value is given to the variable number (right before the start of your loop)? Will this number ever be between low and high when low is positive?

[USEC_OFFICER]

So the problem is to figure out how to modify the code to add parameters?

[TheGuardian001]

Did you read the initial post where it said that the problem was that it wouldn't accept parameters other than (negative number, positive number)?

[Clayton]

To further expand on TheGuardian001's hint: At various points in your code, output the value of each of your variables, see what they are, and what the resulting action in your code is because of that. You should find your answer.

[ToTNuim]

Oh! Now I see! Thank you TheGuardian001 and Clayton !

It WAS my initial value for "number".
But ... ,instead of zero, what should I put as my initial?

[USEC_OFFICER]

What ever number works of course!

@TheGuardian001: I didn't read it fully.
