The simplest way to move a file from one place to another is simply to
rename() it. For instance:

        $old = "HD:Desktop Folder:MyFile";
        $new = "HD:Desktop Folder:MyFolder:MyFile";
        rename $old, $new;

will move "MyFile" into the folder "MyFolder" (provided it exists). You can
watch it happen.

Beware if the folder does not exist, for MacPerl will try to rename MyFile
as MyFolder. The icon remains titled MyFile, but you won't be able to open
the file, and if you try to throw it away you will get an error message
saying that you cannot "because it cannot be found".

The partial ne-naming can be corrected with ResEdit. I am not sure if you
would call this a bug exactly, but MacPerl behaves in a rather unfriendly
fashion under these circumstances.

You cannot (I believe) move files into Trash this way: but if you want to
get rid of the file, unlink() might do what you want perhaps?

You might try something like:

    open(OUT, ">Dev:Console:Hello");
    print OUT "Wait for me!\n";

It is sometimes useful to open additional windows by this means, but I
haven't found a way of closing them however, except manually or via
AppleScript.
