Deleting a document

Had a quick question...

We are able to download files using command line code (get =""), but have not been able to delete those files once downloaded.

Here are a couple of things we have tried,

1) del = ""

2) dele = ""

3) Delete = ""

None of these seem to work. We are working with SFTP on port 990. We tried deleting manually using the FTP Voyager interface and we were able to. So it is not a permission issue, i think.

Any help with the syntax or any insight onto the issue will be of great help.

Thanks a lot.
