`print qq{$_ => $ENV{$_}\n} for sort keys %ENV;` [download] Make the \n a <br> if used in CGI. Cheers, KM	[reply] [d/l]

Simple: `#!/usr/bin/perl use strict; use warnings; print "Content-type: text/html\n\n"; foreach my $k (sort (keys %ENV)) { print "$k: $ENV{$k}<BR>"; }` [download] HTH	[reply] [d/l]

In case it's not clear from the examples above, I'd simply like to point out that $ENV{SOMTHING} is accessing a value from Perl's predefined `%ENV` hash. For a list of all predefined variables, see perlvar.	[reply] [d/l]

from a book I have: `#!/usr/bin/perl5 print "Context-type: text/plain\n\n"; while ( ($key,$value) = each %ENV ) { print "[$key]\t[$value]\n"; } exit 0;` [download]	[reply] [d/l]
