I can sort an array passed into a subroutine, but I can't reverse sort or use a custom sort on that array.

I can't get subroutines to do much of anything with passed arrays. This is one of sevearl array-subroutine tests that I've tried over the last two days. I have tried variations with passing array references, but to no avail.

# test subroutines with an array

$var = 8; push( @TaR, $var ); $var = 2; push( @TaR, $var );
$var = 5; push( @TaR, $var ); $var = 4; push( @TaR, $var );
$var = 5; push( @TaR, $var ); $var = 6; push( @TaR, $var );
$var = 1; push( @TaR, $var ); $var = 8; push( @TaR, $var );

print STDOUT "\n\n"; print STDOUT "\n\nAs-is    ";

# This segment works
for $OneLine( @TaR ) { print STDOUT "    $OneLine"; }
print STDOUT "        Done\n\n";

SortedArray( @TaR );

ReversedArray( @TaR );

print STDOUT "\n\n";

# This sort works
sub SortedArray
{
    my @PassedArray = @_;
    my @SortedArray = sort @PassedArray;
    
    print STDOUT "\n\nSorted    ";

    for $SubLine( @SortedArray )
    { print STDOUT "    $SubLine"; }
    print STDOUT "        Done\n\n";
    return 1;
}

# This sort, but doesn't reverse the sort
sub ReversedArray
{
    my @PassedArray = @_;
    my @SortedArray = sort reverse @PassedArray;
    
    print STDOUT "\n\nRvrsd    ";

    for $SubLine( @SortedArray )
    { print STDOUT "    $SubLine"; }
    print STDOUT "        Done\n\n";
    return 1;
}
