If your FTP server is running on z/OS (i.e. MVS is the operating system), and you are downloading text files, be sure to call SetTypeAscii prior to calling GetFile (or any other method that downloads files). The default mode of Chilkat FTP2 is binary. If a text file is downloaded in binary mode from a z/OS server, you’ll receive EBCDIC text, not US-ASCII. If the mode is changed to ASCII, the FTP server will convert from EBCDIC to ASCII before sending.
