Pascal (Lazarus/Delphi)

Send FTP STAT and Get the Reply

Demonstrates the Chilkat Ftp2.Stat method, which sends the FTP STAT command and returns the server's reply. It takes no arguments; depending on the server and session state, the reply may contain status information or a directory listing.

Background: STAT is unusual in that it returns over the control connection without opening a data connection, which is why some clients use STAT as a lightweight directory listing that sidesteps passive/active data-channel setup. Its exact behavior, accepted arguments, and whether it works before login are all server-dependent, so treat the reply as advisory rather than a fixed format.
