From the SHARP APL/PC Reference Manual V2 February 1985, page 3-2: The <backspace> key in alternate case steps the cursor back but does not erase, leaving the character to be overstruck by the next character entered. If this overstriking produces one of the valid composite APL characters, it remains on the screen.
