qw for variables?
Greetings; I can get qw to work for things like @n = qw( john jacob jingleheimer schmidt ); but something like @n = qw( $names ); doesn't work. I get the literal string $names in @n! What does the equivalent of qw(???) for a variable? Many TIA! Dennis -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: qw for variables?
qw( john jacob $name ) is equivelent to
('john', 'jacob', '$name') notice the single quote. The single quotes does
not interpolate (use the special meanings of special charaters, so the $
doesn't designate a varible name it's just a $ character).

What does the equivalent of qw(???) for a variable? You mean like: my @array = ($var1, $var2, $var3); Jonathan Paton __ Do You Yahoo!?

Greetings; No, I mean if $names contains Jesus Mary Joseph and I do my @n = qw( $names ); I want the same results as if I had done my @n = qw( Jesus Mary Joseph ); Obviously qw() does not work this way, but I can't find the equivalent that does.

Re: qw for variables?
The split did the trick, and cut out a few lines of code also. I had already done some splits and joins to get ready for qw() which I can n ow delete! Thanks for the help everyone! Dennis -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
