Phoenix.pm: Perl 101

[jim mckay]

Look on page 133 of the camel book $" is the list seperator!

#!/usr/bin/perl

$"=",";
@author = ('Tom', 'Randal', 'Larry');
print "@author\n";
print @author;
print "\n";


outputs

Tom,Randal,Larry
TomRandalLarry


VERY COOL! This is gona save me tons of time in formatting output..
