in reply to Passing scalars to CGI module

First, let me idly suggest that you re-consider your data structure to use a hash of hashes instead of a hash of arrays. Named lists are LOTS easier to use in situations like yours: your code will become more self-documenting, easier to modify (adding elements is bunches easier), and easier to understand 6 months from now.

But back to your problem: suppose you did this: 


%sample    = 
(
'login' =>["Login", 75, 'textfield', 'login'],
'last' =>["Last Name", 75, 'textfield', 'last'],
'first' =>["First Name", 70, 'textfield', 'first']
);

...where $sample{'login'}[2] is your CGI method and  $sample{'login'}[3] is the fieldname. Or better yet: 
%sample=
(
'login' =>{name=>"Login", width=>75, method=> 'textfield', field=>'log
+in'},
'last' =>{name=>"Last Name", width=> 75, method=>'textfield', field=>'
+last'],
'first' =>{name=>"First Name", width=>70, method=>'textfield', field=>
+'first'}
);

That way if you wanted to access the default param of 'last' all you'd have to do is: 
print $q->$sample{'last'}{'method'} ($sample{'last'}{'field'});

or somesuch.

    Okay, I understand your point about hash of hashes. So,... 
    %sample=
(
'login' =>
  {name=>"Login", 
   width=>75, 
   method=> 'textfield', 
   field=>'login',
   size=>'10',
   max=>'8'
  }, etc...
);

    Now, to generate the <INPUT TYPE="text" NAME="login" VALUE="" SIZE=10 MAXLENGTH=8> HTML code, I would do that by: 
    $q = new CGI;

print $q->$sample{'login'}{'method'}->($sample{'login'}{'field'},
            $sample{'login'}{'size'},
            $sample{'login'}{'max'});

or do I need to do the following:

print $q->$sample{'login'}{'method'}->(-name=>$sample{'login'}{'field'
+},
            -size=>$sample{'login'}{'size'},
            -max=>$sample{'login'}{'max'});

    Ultimately, I want to be able to do something like the following. 
    @report = ('last','first','phone','payment');

foreach (@report)
   {
   print qq|<tr><td width="$sample{$_}{'width'}">$sample{$_}{'name'}|;
   print $q->$sample{$_}{'method'}->(-name=>$sample{$_}{'field'},
            -size=>$sample{$_}{'size'},
            -max=>$sample{$_}{'max'});
  print qq|</td></tr>|;
   }
