Hello ImJustAFriend,

Because you haven’t explicitly stringified the expession $provinfile.$server, the dot functions as a concatenation operator. So the result is a string, but there is no dot character inserted between the two strings. This is obscured by the error message, which does contain an inserted dot character.

Update: It’s good practice to ensure that an error message reflects exactly what’s happening. Here, you can accomplish this with an extra assignment:

for my $server (@servers)
{
    my $full_path = $provinfile . '.' . $server;    # or = "$provinfil
+e.$server";

    open IN2, '<', $full_path
        or die "Could not open Server IN2 ($full_path): $!\n";

    ...
}
