But the problem is the following:
the user has to enter an url and now i want to put "http://"; always in
front (and show it on the screen) so that the user doesn't have to
enter this everytime.
How about:
chomp( my $input = <>
Thanks!

You could possibly shorten this last line to:
$question ||= $default;
This will set $question to $default if $question logically evaluates to
false (which includes the case where $question is the empty string). If
you only want to reset $question whe

Hi,
Just out of interest, could you do it this way:
my $default = "/foo/bar/blat";
print "File to use? [$default] ";
chomp(my $question = || $default);
I've just started using this sort of approach to assign default values to
undefined/null parameters, eg:
my $age = param('age') ||

Most programs do it like so:
my $default = "/foo/bar/blat";
print "File to use? [$default] ";
chomp(my $question = );
$
I usually display what the defaults are at first and then use a carriage
return to signify that is what I want.
You can test like:
if ( $question eq '' ) {
# place the default value into $question
}
I usually use a infinite loop and when values
