Hello Cleware and welcome to the monstery and to the wonderful world of perl!

I suspect nothing is wrong with your import: the error Undefined subroutine &main::Print refers to your statement Print($return); infact in perl you have print not Print and no parens are needed (or you'll get another error like print interpreted as function at.. ).

Also do not never forget to use strict; use warnings; at the top of your perl programs.

As per the Win32::API docs is good to check if the import was done (the two die in the below code):

use Win32::API;
$function = Win32::API::More->new(
    'mydll', 'int sum_integers(int a, int b)'
);

#### $^E is non-Cygwin only
die "Error: $^E" if ! $function;
#### or on Cygwin and non-Cygwin
die "Error: ".(Win32::FormatMessage(Win32::GetLastError())) if ! $func
+tion;
