SPUG: undef a list of variables?

[David Bitseff]

If you mean a list you can clear a list with '@list = ();'.  You can
also use undef on a list 'undef @list;' If you mean scalars in a list,
you could put use a foreach loop and then undef each of them:

----------------------

for (@scalars_list)
{  undef $_ }

---------------------
or
----------------------------------

for ($scalar1, $scalar2, $scalar3)
{ undef $_ }

----------------------------------

You can also assign undef to a variable '$_ = undef;' I'm not sure why
you would want to do this between method calls on a blessed variable.
Are you using the strict pragma?
