I am using input querey to ask for a value, how do i made it ask for a integer rather then a string? The code I am using:
Simba Code:Procedure AskGuess;
begin
If (InputQuery('Guess number', 'Number', Guess)) Then
begin
writeln(Guess);
end;
end;

I'm not 100% sure i understand your problem though
You can convert the answer to integer with StrToIntDef().
didn't work :9Quote:

What did you do with it? Post the code.Quote:

lol...you read a post not by me and thought it's me..Quote:

Yeilds the same result
Simba Code:Program Game;
const
RANDOM_PICK = 100;
var
Number,Tries,GuessInt:Integer;
Response,Guess:String;
Procedure AskGuess;
begin
If (InputQuery('Guess number', 'Number', Guess)) Then
begin
Writeln(IntToStr(Guess));
end;
end;
Procedure PickNumber;
begin
Number := Random(RANDOM_PICK);
Writeln('' + StrToIntDef(Guess);
AskGuess;
end;
Begin
PickNumber;
end.
Because you still have this.Quote:

got it thanks!Quote:

You'll get a type mismatch error. On this case, you already specified Guess as a string so there is no need to transform it as writeln writes...strings.
Writeln does not just write strings ;)Quote:

My point was much more rhetoric than technical, seeing variant as "integers + strings", therefore it isn't virtually incorrect to say that writeln only writes strings. Awful joke coming from a sleep deprived person.Quote:

huh...i still don't get why you say writeln writes only strings and why variant should be used...Quote:

I don't think there is any function out there, in any language, that can just print the string/literal equivalent of something without some sort of lexical casting somewhere along the lines.
It's probably why Implicit concatenation doesn't happen:
Simba Code:writeln("Foo: " + someint); //compile time error.
but explicit does:
Simba Code:writeln("Foo: " + ToStr(someint));
Some languages have explicit concat or aren't type strict.
