khelben has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks,
some days ago I asked for help with long strings. Thank You a lot.
But how can I get some interaction?

I have red something about formulars in Perl/CGI, but i have not got useful examples for my problems. I know how to do this in c++ with X/Windows, but not in Perl/CGI on the Web(browser)

I need a value (integer >0) stored in a variable. Like here:
Number(1..20000)?:_________

Then some "Radiobuttons" with a text on each button and 1 row where I can choose 1 from n possibilities and another row where I can choose m from m possibilities.
Then a button to say, that all the input has been done an the script can compute a result and last not least an outputtextbox for the result with the possibility tho have scrollbars.

Do You know a good source of examples for some code or do You have some useful help for me?

Best wishes and thanks,
Roman

update (broquaint): title change (was Formulars and some interaction)

    Hallo Roman,

    You say you need some forms and radio buttons, are you sure you are not looking to print HTML?
    Have a look at CGI.pm, a tool which will help you print out HTML and parse submitted HTML forms.

    I need a value (integer >0) stored in a variable. Like here:
    Number(1..20000)?:_________

    Im not quite sure what you mean here, you need an integer stored in a variable?
    $variable = 42;
    Can you rephrase?

    In any case, examples of doing this kind of thing, if I have understood your question correctly, can be found in abundance in the CGI.pm documentation.

      This works good, thanks!
      use CGI qw/:standard/;
   print 
       header,
       start_html('Simple Script'),
       h1('Simple Script'),
       start_form,
       "What's your name? ",textfield('name'),p,
       "What's the combination?",
       checkbox_group(-name=>'words',
                      -values=>['eenie','meenie','minie','moe'],
                      -defaults=>['eenie','moe']),p,
       "What's your favorite color?",
       popup_menu(-name=>'color',
                  -values=>['red','green','blue','chartreuse']),p,
       submit,
       end_form,
       hr,"\n";

    if (param) {
       print 
           "Your name is ",em(param('name')),p,
           "The keywords are: ",em(join(", ",param('words'))),p,
           "Your favorite color is ",em(param('color')),".\n";
    }
    print end_html;

      Maybe: "What's your name? ",textfield('name'),p,
      Here i need a number.
      Can I change the text of the button "Submit Query"?
      How can I put the output in a textfield with scrollbars?

        A textfield will take text including numbers, it is up to you to check if the user submitted a number on the server. As for changing the button text: 

        use CGI ':standard';
print submit( suggestion => 'RTFM' );
__DATA__
<input type="submit" name="suggestion" value="RTFM" />
