in thread WWW-Search module that works

The line of code displayed by the debugger is the line it's about to execute, not the line it just executed. Hit 'n' one more time, then x my $sQuery, and you should see the value you assigned to $sQuery.

    so far
    DB<1> n main::(ysam5a.pl:10): my $sQuery = 'Columbus Ohio sushi restaurant'; DB<1> n main::(ysam5a.pl:11): my $oSearch = new WWW::Search('AltaVista'); DB<1> x $sQuery 0 'Columbus Ohio sushi restaurant' DB<2> n main::(ysam5a.pl:13): $oSearch->native_query(WWW::Search::escape_que +ry($sQuer )); DB<2> x my $oSearch 0 undef DB<3> n main::(ysam5a.pl:14): $oSearch->login($sUser, $sPassword); DB<3> n main::(ysam5a.pl:16): while (my $oResult = $oSearch->next_result()) main::(ysam5a.pl:17): { DB<3> n main::(ysam5a.pl:20): $oSearch->logout; DB<3> x my $oResult 0 undef DB<4> n Debugged program terminated. Use q to quit or R to restart, use O inhibit_exit to avoid stopping after program termination, h q, h R or h O to get additional info.
        I have WWW::Search installed but not WWW::SearchResult I am on activeperl 5.8.6 which repository has it?
      When you say "x my $oResult" it means to create a NEW variable, local to just that one debugging command, and display its value, which is of course undefined. If you just say "x $oResult" it will display the correct value.
      Incidentally, I just ran your program under perl 5.8.8 on a Linux box, installing WWW::Search::AltaVista (and Yahoo as well) from CPAN. It works fine for me. You might have run into a Windows (or ActivePerl) compatibility issue. Sometimes it helps to use the version of Perl that runs under Cygwin .
