Set the FTP Transfer Type to ASCII

Demonstrates the Chilkat Ftp2.SetTypeAscii method, which sets the FTP representation type to ASCII for subsequent transfers. It takes no arguments.

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: ASCII mode translates line endings between the client and server conventions (with CrlfMode able to apply further conversion on download). It is a legacy behavior that is rarely wanted today — binary is recommended for essentially every file, text included — and it silently corrupts binary content such as images and archives. Use it only when line-ending translation of plain text is specifically required, and switch back with SetTypeBinary afterward.
