Use the STARTDIRECTORY statement to specify which file system is initially used when a new user logs in.
.-STARTDIRECTORY MVS------. >>-+-------------------------+--------------------------------->< '-STARTDIRECTORY--+-HFS-+-' '-MVS-'
STARTDIRECTORY HFS
The value of STARTDIRECTORY must be compatible with the ANONYMOUSFILEACCESS value when anonymous logins are enabled and ANONYMOUSLEVEL is 3 or greater.
For example, if ANONYMOUSLEVEL is 3, ANONYMOUSFILEACCESS is MVS, and STARTDIRECTORY is z/OS UNIX, anonymous users receive a filetype error when they attempt to log in to FTP. The anonymous login is rejected by the FTP server.
