in reply to Read a variable backwards..

G'day sathya83aa,

I see a number of solutions involving breaking the string into individual characters and then recombining in reverse order. This isn't necessary as reverse in scalar context will do this for you.

When the context is already scalar, you can just use the reverse function:

$ perl -le 'my $x = "8940163...835"; my $y = reverse $x; print $y' 538...3610498

In list context, you can force scalar context with the scalar function:

$ perl -le 'my $x = "8940163...835"; print scalar reverse $x' 538...3610498
