Ending an Editing Session

When you finish editing a particular file, you can enter a FILE or QUIT subcommand for that file. The file is removed from the ring, and the previous file in the ring is displayed.

To end the editing session for all of the files and return control to CMS, use the CANCEL macro, as follows:
====>  cancel
Entering the CANCEL macro is equivalent to entering a QUIT subcommand for each file in the ring. If you modified any of the files, the usual warning message is displayed for each of those files:
File has been changed; type QQUIT to quit anyway

You can then enter either QQUIT or FILE.

If none of the files being canceled were modified, control returns immediately to CMS.
