DESCRIPTION
Note: The
MPE/iX implementation of this utility does not function exactly as this man page de-
scribes. For details, see the MPE/iX NOTES section at the end of this man page.
There are two components to vi: a screen editor (Vi), and a line editor (Ex). Each has a dif-
ferent set of commands; you can invoke the line editor from within the screen editor and con-
versely, you can invoke the screen editor from within the line editor.
In the screen editor, you are in either insert mode or command mode. In command mode, every
character you type is immediately interpreted as a command. In insert mode, every character
you type is added to the text that you are editing.
There are two ways to start your session in Ex mode: you can invoke the command under the
name ex; or you can invoke it under the name vi but specify the –e option. Similarly, there
are two ways to start your session in Vi mode; you can invoke the command under the name
vi (without specifying –e); or you can invoke it under the name ex but specify –v.
