Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question: to be more precise. Here is the code of a sub
get_handles returns the handle for the args specified. These args are stored as hash/key pair in a file Call to the sub is made via interface_control($s) MY question is , i want to specifically access, one of the element in the array @r, say only $r[0]. Is there a way to access this or pass any reference to interface_control call
