XEDIT

XEDIT is a visual editor for VM/CMS using block mode IBM 3270 terminals.   (Line-mode terminals are also supported.) XEDIT is much more line-oriented than modern PC and Unix editors. For example, XEDIT supports automatic line numbers, and many of the commands operate on blocks of lines. One of the features is a command line which allows the user to type arbitrary editor commands. Because IBM 3270 terminals do not transmit data to the computer until certain special keys are pressed [such as ↵ Enter, a program function key (PFK), or a program access key (PAK)], XEDIT is less interactive than many PC and Unix editors. For example, continuous spell-checking as the user types is problematic.
