How to chmod a remote file (Make it executable)?

After uploading a perl script I want to make it executable.
To do so I have to chmod (change attributes).

How do I do this with SmartFtp ?

In addition to my previous question:

Is it possible to add a column in the remote file listing pane
indicating the file attributes in UNIX style?

Hi, for the 1st post, right click over desired remote item, properties/chmod, for the second post, right click over a emphy space on remote browser view->select details permisions.
