The form 'my $name0="c:/test"' is both a declaration (you can only do
the 'my' for a variable once) and an assignment (the :="c:/test" part)
which you can do as often as you like.
Only use 'my' the first time. Or alternatively do a separate declaration
and assignment of value, i.e.
my $name0;
Then just do '$name0="c:/test";' whenever you want to change the value
of $name0.
