Subject: passing an argument to a subroutine
Hello
An argument passed to a subroutine returns wrong value.
Code example:
@x = (1..5); [Mike: @x = (1,2,3,4,5)]
$x = @x; [Mike: $x = 5, the number of elements in @x]
showValue ($x); # or showValue (\$x); [Mike: pa

In both cases, the script prints out 1.

Hello
An argument passed to a subroutine returns wrong value.
Code example:
@x = (1..5);
$x = @x;
showValue ($x); # or showValue (\$x);
sub showValue {
my $forwarded = @_;
print $forwarded; # print ${$forwarded};
}
In both cases, the script prints out 1.
