AFAICR, each key definition only took up the minimum possible amount of
space in the buffer, and if the total size exceeded 255 bytes, the
attempt to define the expansion which would have gone over the limit
failed with a 'Bad key' error. But I haven't tried this in years and I
don't have an emulator handy to experiment with.
