The global variable $" contains the separator, though it's often clearer to use join:

use 5.010;

# this has the same effect as...
{
    local $" = ', ';
    say {$fh} @array;
}

# a shorter approach
say {$fh} join ', ', @array;

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
