Re: Question about concatenationby LanX (Canon)

the dot . is a scalar operator expecting something convertible to a string.
from perlop: Binary "." concatenates two strings.
print operates on lists and the comma is the necessary list operator to delimit the elements.
print "Counting up: " . join ( "", 1..6 ) . "\n";
