I need to pass three arrays to a subroutine (the arrays may change based on certain conditions). What I have but doesn't work: 
sub myCurve(@@@$$);
$my_exp = myCurve(\@my_arx,\@my_ary,\@my_arz,$my_v1,$my_v2);

sub myCurveX(@@@$$)
{
my $my_y = pop;
my $my_x = pop;
my ($my_xar,$my_yar,$my_zar) = @_;
my @local_x = @$my_xar;
my @local_y = @$my_yar;
my @local_z = @$my_zar;
# do some stuff
return $my_calc;
}

My scalars get passed and I can manipulate them, but the arrays seem to be void. I have looked at lots of examples and tried a number of ideas, but nothing seems to work. I really appreciate in advance any advice/help.
