INed Editor User's Guide Chapter 2. Working with a file or directory is called an editing session . You can start an editing session either by creating a new file or by accessing an existing file or directory. When you want to type new information such as a letter, memo, or program, you must create a file.
Text files contain only sequences of characters.
Structured files store specialized data and contain a history, which you can use to recover past versions of the file. Structured files may become quite large after several changes. You can use commands such as the ghost command, newfile command, and rmhist command to work with structured files. While you are editing the file, you can save changes without ending the editing session. You can also make a copy of the file you are editing by saving it in a different file, or, using the Print menu, print the file or append it to another file.
