Dear monks,

Now, I have another question, how can I clear the *b when undef the *a, in the above scenario?

That is, when doing 

*b = *a; 
undef *a;

[download]
The contents of *b is not cleared. Is it possible to clear that too with the help of glob?

Yes, ofcourse without using undef *b; And also, it is understood that undef $a; or undef @a will affect $b and @b.
