Re^2: Improve My Code...

Thanks for your suggestions, I appreciate it. This all made sense except one thing.. why when I change my pattern-match variables from arrays to scalars (@rain to $rain = $page +~ /.../ for example) do I need to have parentheses around them to get the output I want. Does it have something to do with scalar vs list data? Thanks again!

Does it have something to do with scalar vs list data? Indeed it does. In scalar context (`my $var =`) a match regex returns true or false. In list context (`my ($var) =`) a match regex returns the list of captures. You are interested in just the contents of the first capture so: `my ($var) = $page =~ /...(...).../;` [download] is the appropriate syntax. Update: provide complete code line to illustrate appropriate list context usage. True laziness is hard work	[reply] [d/l] [select]

Indeed it does. In scalar context (my $var =) a match regex returns true or false. In list context (my ($var) =) a match regex returns the list of captures. You are interested in just the contents of the first capture so:

my ($var) = $page =~ /...(...).../;

is the appropriate syntax.
