wishes to keep the old sequence, they need only to press

<ENTER>. Otherwise, they should

press backspace to delete the old characters, then enter the new sequence and press
<ENTER>. If for some reason the selection is unacceptable, an error message will appear and
the sequence will revert to the old character values. The escape sequence is stored with the
user profile, therefore it is possible to have different sequences for different users. A hardcoded
escape sequence is provided in the event that the programmed sequence is lost. It is semi-
colon, exclamation, semi-colon, exclamation or

‘;!;!’ none of these characters should echo

and no

<ENTER> is required.


Appendix F lists the hexadecimal codes for the ASCII character set.

buffer.
