GLOBAL Variables with qw()

[Icecrack]

Thanks in Advance,

when declaring GLOBAL Variables can we use qw() ?

example:

my qw($data $id $test $var);

etc.


i will be testing this but if any one knows with in the next 1 hr please post

Thank You,

'my' is used to declare local variables. To declare multiple variables at once, you may use:

my ($data,$id,$test,$var);

qw() can be used only on RHS of any assignment statement, as in:

my @a = qw(ad sat d f g);

Charlie,

There seems to have been a little misunderstandin g 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.

$foo = 'test';
my @list = qw($foo);
print $list[0];

prints $foo

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 Note that "vars" is obsolete but still supported.
