I am not using "use strict" option here because it gives compliation error stating variable not defined.

To to be able to use strict, use our $FLAG_IPV4; in your program.

Can anyone help me understanding how that values are coming from the file to above print statement

eval EXPR. "In the first form, the return value of EXPR is parsed and executed as if it were a little Perl program." Of course, EXPR, in this case, is the contents of the "config" file.
