Re^2: how can I use regular expresion if my string to be matched has round brackets

why it works with

my $ipn=qr/\( going \) there/;
or
my $ipn=qw/\( going \) there/;
[download]

but it doesn't work with

my $ipn="\( going \) there";
[download]

Thanks.

You need: `my $ipn="\$ going \$ there";` [download] The \\ gets replaced by \ when the string is parsed. Perl reduces RSI - it saves typing	[reply] [d/l]
