I use the CGI module as,

use CGI;

$query = new CGI;

$pghead = $query->param ('pghead');
$WelMsg = $query->param ('WelMsg');
...

Suppose I want to print all the keys & values from the form, (other than read one by one) what do I do?

You're welcome.

Did you have difficulty finding the section on
FETCHING THE NAMES OF ALL THE PARAMETERS  PASSED  TO  YOUR SCRIPT:
in
perldoc CGI
?

Or an even simpler method:

  $query->save(STDOUT);

That was really helpful. In "perldoc CGI", I found what I needed and a lot more! (But some of it went over my head !!!)

There was something abt "passing parameters to a namespace..." What is a namespace?

Hope I am not asking too much from a 20-point question...

Thanks indeed.
