in thread How do i refresh a page from the perl script.

With -w enabled you can't use params like that without getting uninitialized value warnings when the params aren't defined. Also $q->param{'Address'} shouldn't have curly braces but parentheses: $q->param('Address').

This version shows a way to properly initialize the variables whether the params exist or not.

#!/usr/local/bin/perl -w use strict; use CGI; my $q = CGI::new(); my $name = $q->param('Name') || ''; my $addy = $q->param('Address') || ''; print $q->header; print <<HTML; <form> Name: <input type="text" name="Name" value="$name"> Address: <input type="text" name="Address" value="$addy"> <input type="submit" value="Refresh"> </form> HTML

[stevieb]: interestingly enough, someone else got my Devel::Examine:: Subs distribution for their PRC, and I applaud the change. This dist is extremely complicated and mostly obfu, but the person doing it understood PPI enough to change...
[stevieb]: ...something I had overlooked in the extreme depths of the core functionality. After merging, then a couple of extra tweaks, I still have 100% test coverage. Yay for people who write tests!
