"dir" is a builtin of command.com.

If you really want "dir", you'll have to use

BEGIN {system("command /c dir")}

ls (on the other hand) is an external to bash, so you can
say

BEGIN {system("ls -lA")}

As to printing a 0, you do know that system returns the exit
status, not the output of the command, don't you?
