I expected the info in BAP to be identical to that in BAD, so I didn't
bother looking.  Shame on me.  I'll check out my copy of BAP to see if
there are any additional insights.  Thanks for the tip!

None.  I've looked.  Or at least, I've looked in the DOS Manual, which
came with the Disk ][.  Was there any other?  Perhaps one of those smaller
booklets that Apple used to send out with their hardware in the 1977-1978
timeframe?
