Expand|Select|Wrap|Line Numbers
  1. my qw($data $id $test $var);

'my' is used to declare local variables. To declare multiple variables at once, you may use:
Expand|Select|Wrap|Line Numbers
  1. my ($data,$id,$test,$var); 
  2.  
qw() can be used only on RHS of any assignment statement, as in:
Expand|Select|Wrap|Line Numbers
  1. my @a = qw(ad sat d f g);
  2.

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.

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.

Expand|Select|Wrap|Line Numbers
  1. $foo = 'test';
  2. my @list = qw($foo);
  3. print $list[0]; 
prints $foo

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 Note that "vars" is obsolete but still supported.
