Well, I did try the following test before putting "%$search%" into the snippet suggestion in my own reply: `perl -Mstrict -le 'my $s="blah"; print "%$s%"'` [download] which prints "%blah%". Putting a "%" in front of a scalar variable in a double-quoted string will not turn that variable into a hash ref. If the variable happens to already be a hash ref, then of course it will be interpolated as such, though not in a way that most folks would consider useful: `perl -Mstrict -le 'my $s={foo=>"bar"}; print "%$s%"'` [download] prints something like "%HASH(0x1801380)%". It's only arrays (and array refs) that get interpolated into the list of values when placed inside double-quotes -- and only if the sigils are right: `perl -Mstrict -le 'my %s=(foo => "bar"); print "%s"' %s perl -Mstrict -le 'my $s=[qw/foo bar/]; print "%$s%"' %ARRAY(0x1801380)% perl -Mstrict -le 'my $s=[qw/foo bar/]; print "@$s@"' foo bar@` [download]	[reply] [d/l] [select]

Ah, well, that's what I get when I comment without testing.... ;^( I knew I got smashed before with a %, I just thought it was like $ and always messed it up. Thanks for the clarification. Now I can use % in my messages again! ...roboticus	[reply]
