Subject: Revised: Symbolic References & "use strict;"
Hi!
I'm writing a program that uses "use strict;" (which requires the variable
to be declared before it's can be used) and symbolic references (e.g.
$$cmd{$ext}++;).
When I run the program, I get the error saying I must declare the variable
$$cmd first.
Please let me know can I solve this problem without removing "use strict;"
from my program.
Thanks,
Andy
