Get the FTP Server System Type (SYST)

Demonstrates the Chilkat Ftp2.Syst method, which sends SYST and returns the server's operating-system type reply. It takes no arguments.

Background: The SYST reply (for example UNIX Type: L8 or Windows_NT) hints at how the server formats things like legacy directory listings, which historically varied by platform. Chilkat uses it internally to parse such listings; you rarely need to call it directly, but it is useful for diagnostics or when adapting to an unusual server.

local ftp = chilkat.Ftp2.new()

ftp.hostname = "ftp.example.com"
ftp.username = "myFtpLogin"

-- Normally you would not hard-code the password in source.  You should instead obtain it
-- from an interactive prompt, environment variable, or a secrets vault.
ftp.password = "myPassword"

-- Connect and log in (Connect performs both).
