[VPM] regular expression line number in string

[Jeremy Aiyadurai]

hello all perl guru's

in a regular expression how do I retrieve the line index/number of a match 
in a multiline(\r\n) string?

eg.
-------------------

my $line = "asdasdasdasdasdasdasdasdasdasdasdasdasdasdasd
asdsadasdasdasdadasdasdasdasdasdasdhereaSDASDAS
asdasdasdasdasdasdasdasdasdasdasdasdasdasdasd";

$line =~ m/(here)/ig;

------------------

Thanks in advance for your help.
