When you are logged into the shell, you have a choice of editors to use to create and change files, depending on which terminal interface you are using, OMVS or the asynchronous terminal interface. For details about the editors, see Editing files.

If you are using NFS from your workstation, you can edit z/OS UNIX files directly with your editor of choice.

When you create directories and files, you can control access to them. Whenever you want, you can change the access permissions that are set when you first create a directory or file. See Handling security for your files for more information about access permissions.
