in thread Web form to alter files is writing to file before submit button is pressed.

I often use CGI::Minimal to see what is going on with form inputs. It has a handy function called "calling_parms_table()" which returns a HTML table of all form and environment variables. It will show you what happens when you hit Enter instead of pressing the button - the result seems to vary across different browsers. This becomes important if, say, you had two buttons on the form: make_changes and undo_changes.

    "calling_parms_table()"

    CGI/CGI::Simple provide 

    my $q = CGI->new; 
print $cgi->header(), $q->dump, '<hr>', CGI->new( \%ENV )->Dump;

    I don't think I'd use CGI::Minimal, it appears to be too not well tested, the bug cue is very empty
