in reply to Implicit assignment to $_

Hi, I am unsure about what you are trying to achieve here as there is very little of the code.

$_ is a global variable and quite a few places in perl use $_ as the default.

To know more use 'perldoc perlvar' and you will have a good explanation of where and how $_ can be used.

Below is a small program that uses $_ as the default for both the while loop and the print statement.

I hope this helps.


use strict; use warnings; use autodie; while(<DATA>) { print; } __DATA__ Test A Test B
