Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

KEY CODE ALREADY DEFINED.
ENTER A DIFFERENT KEY CODE.
 
Either the key code you attempted to assign has
already been assigned, or it has the same first
letter as the one-letter key code of another
style on this style sheet. For example, if "K" is
an assigned key code, you cannot assign "KA" to
another style.
 
▐ Assign a different key code.
