Hello everyone, I am trying to sort an array returned by a subroutine.
I realize it would be better if the subroutine returns a Sorted Array instead of Sorting the Returned Array, however I would like to know why sort doesn't work on a Returned Array and why the returned array has to be parenthesized.
#sortarray.pl print join("\n",sort arraytest() ),"\n";
#This works --> print join("\n",sort (arraytest()) ),"\n";
#Don't know why this works --> print join("\n",sort &arraytest() ),"\n";
sub arraytest()
{
my (@array) = qw( 1 2 3 9 8 7 );
return @array;
}Thanks. -gohaku
