OVERSTRIKE MODE

 Sets the mode of the current buffer to overstrike, as opposed to insert.

 o  As you type, the new text replaces existing text at the current
    position -- hence, overstrike mode is sometimes called "replace mode"
    or "type-over mode."

 o  The mode of the buffer is shown in the status line.  It also affects
    the following commands and keypad functions:

       DELETE                EDT Delete Character key (COMMA on keypad)
       ERASE CHARACTER       EDT Specins key (GOLD-KP3)
       QUOTE                 WPS Delete Character key (PF4)
       RESTORE CHARACTER

 o  To change the mode of an unmodifiable buffer, first use the SET BUFFER
    MODIFIABLE command.
