I am trying to write a subroutine that is to be passed a hash of items to be printed out. I am currently using something like this:
sub loop_print2 {

	local(%arg=$_[0],$key);
	foreach $key (sort keys %arg) {
		print "$key:\t$arg{$key}\n";
	}
}
I am calling it like this &loop_print2(%c); where %c is a hash that is already populated from a previous function call. I am also trying to find out how to return a hash from a function. Can I build it up and then use something like:
return %c;
at the end of the subroutine? Thanks for any help on this!
