I would like some advise please, about warning errors that are being logged. The 'shebang' line and modules

#!/usr/bin/perl -wT

use CGI qw/:standard/;
use DBI;
use Net::SMTP;
use CGI::Carp qw(fatalsToBrowser);

BEGIN {
     use CGI::Carp qw(carpout);
     open(LOG, ">>/home/username/cgi-bin/mycgi-log") or
       die("Unable to open mycgi-log: $!\n");
     carpout(LOG);
   }

# resource limits
$CGI::DISABLE_UPLOADS = 1;
$CGI::POST_MAX = 1024;
[download]

The first line in the log file

Unquoted string "footer" may clash with future reserved word at line 714.

print footer;
[download]

So, I will call it "page_footer" or something I guess.

The next line in the log file

Unquoted string "break" may clash with future reserved word at line 716.

sub check_value_combinations {

diehtml($comb_error) if defined $comb_error;
print footer;

break;
}
[download]

Is this one caused by the footer problem, or , if not, what else do I put in place of the 'break' ?

Name "main::LOG" used only once: possible typo at line 10.

BEGIN {
     use CGI::Carp qw(carpout);
     open(LOG, ">>/home/username/cgi-bin/mycgi-log") or
       die("Unable to open mycgi-log: $!\n");
     carpout(LOG);
   }
[download]

Line 10 , is the "open(LOG, .." code

Use of uninitialized value in concatenation (.) or string at line 256.

print "<form><input type=\"hidden\" name=\"confirmed\" value=\"yes\">"
+;
    print "<input type=\"hidden\" name=\"name\" value=\"$name\">
    <input type=\"hidden\" name=\"surname\" value=\"$company\">
[download]

Line 256 is the second PRINT command, and there are many input lines, the last is finished with a \n"; . The var $name is defined early in the form

$name = cgi_get('name') and $name =~ s/'`-\w\s//go; # filter name
[download]

The only other question I had concerning the script is, just after the 'shebang' line, there is the use of modules Net::SMTP and CGI::Carp , which of course are needed, but what are the other modules used for, and the 'resource limits' code

use CGI qw/:standard/;
use DBI;

# resource limits
$CGI::DISABLE_UPLOADS = 1;
$CGI::POST_MAX = 1024;
[download]

Should anything be changed in the above code, or additional lines needed ?

Thanks, :)
