    ;Re-defining class FOO (previously from file DSK:EB;FOO 1)
    (in file DSK:EB;FOO 3)
    ;Overwrite the existing class? (Y or N) y  (Yes)
    now load in the new FOO file again, and it says
    ;Re-defining class FOO (previously from file DSK:EB;FOO 1)
    (in file DSK:EB;FOO 3)
    ; etc.
Fixed now in EXTEND 287 and EXTSTR 91.  (Installed on MC and ML,
but not install yet on AI since its network program seems broken).
What a long-dormant bug!  Not only was the parity of the answer
from the (Y or N) question being inverted, but even if you had
typed "N" (which would have been mis-understood to mean yes),
it still didn't redefine things right.
