The CHANGE command puts EDT in change mode.  Use change mode to edit at
 the character level rather than the line level.

 Format: CHANGE [range] [;nokeypad command(s)]

 The optional range specifies the cursor position when you enter change
 mode.  If you omit range, the current position is used.

 There are three submodes of change mode.  Which submode you use depends
 on the type of terminal you are using and whether or not you wish to use
 the auxiliary (numeric) keypad for editing commands.  These modes are:

     1.  Hardcopy mode
     2.  Keypad mode
     3.  Nokeypad mode

 If the CHANGE command contains a semicolon (;) it may be followed by
 nokeypad commands.  If the last nokeypad command is EX, EDT returns to
 line mode for the next command line.  This is the only form of the
 CHANGE command that may be used in a startup command file or macro.
