Is there anyway I can get a "Yes" or "No" from a user without having to leave a sub to process the results?

Example:

sub {

blah blah

my $answer = USER INPUT - YES OR NO

process my $answer

}



I keep thinking that the answer may lay in having another function which is called to gather the input, then return this to my sub calling the funcion:

sub {

blah blah

my $answer = &UserInput();

process my $answer

}



What should &UserInput() look like??

Do you want the yes/no to be defined before, or to be run in real time when they run the function? If you want it to be pre-defined, how about a uiser variable?

Hi Andy,

No, this is a "Confirm you want to delete?" type of thing... so input on the spot type of thing.

I was thinking of an alert box in the browser, but I am not sure all browsers support that, or even if that will work in this case?

I am going to try something based on this:

<script>
var x=window.confirm("Are you sure you are ok?")
if (x)
window.alert("Good! - carry on with the rest of the sub")
else
window.location ="somehow leave this sub :-("
</script>

If anyone has any suggestions on how to complete this, or better solutions, I'd love to hear.

Maybe some form of:

my $input = <STDIN>;
chomp($input);


??
