'my' is used to declare local variables. To declare multiple variables at once, you may use:
qw() can be used only on RHS of any assignment statement, as in:

Charlie,

There seems to have been a little misunderstanding about what the Experts area is for.

Not a problem. I can move this thread for you, but technical questions still go in the relevant technical forum.

The Experts forum is for directing the attention of other experts to a tricky problem thread, or discussing issues related to the experts generally.

1. my qw($data $id $test $var);

etc.

If you look up qw in perl operators you will see it also does not interpolate variables. In other words, its the same as using single-quotes, so scalars will not be interpolated when used in a qw list.

prints $foo

1. use var qw($test $perl $var $etc);

Yes that is OK, because it supplies a list to the vars pragma. Note that "vars" is obsolete but still supported.
