When you use the "Append" mode to add data to an existing sequential file, the
length of the file (# of blocks) recorded in the directory ends up greater than
the actual length of the file.  The BAM is correct, as is the file; only the
length info in the directory entry is wrong.  This seems to cause no problem
other than displaying the wrong length.  If you add up the free blocks (after
a "validate") plus the lengths of the files, you get "more" than 664!!  I 
called Commodore and asked; they said they just found out about append mode
a few months ago, and do not yet support answering questions about it!  How's
that for a well informed customer support staff.  Next thing, they'll be telling
me they don't know what the "&" command does.
