Function Arguments

    18     my ($pwd,$i)=($_[0],$i++);

• This is noteworthy for another reason:

    13     &xcopy($source_directory,$target_directory);

• That second argument is never used

• The function only works because it happens to be in the scope of $target_directory

• If it were in a different file, it wouldn't work

• $target_directory is effectively a global variable here

• (Note to use strict freaks: use strict will not help here)
