CHD/CHX Change working data directory / Change working execution directory chd &replstart;pathlist&replend; chx &replstart;pathlist&replend; These are shell "built in" commands used to change OS-9's working data directory or working execution directory. Many commands in OS-9 work with user data such as text files, programs, etc. These commands assume that a file is located in the working data directory. Other OS-9 commands will assume that a file is in the working execution directory. NOTE: These commands do not appear in the CMDS directory as they are built-in to the SHELL.
