It has to be continuous, and for a partition used as a subdirectory
has to also 1) start at a 40-block boundary (i.e. from the start of
a track) and 2) the size must be N*40 blocks (N >= 1, but N>1 makes

I can't check this right now, but I think it simply was the starting
T&S bytes just as for plain files. The size is in the size bytes.

Only within the selected partition/subdirectory. The bitmap for a
subdirectory has the outside area and the allocated blocks of the
subdirectory's directory track marked as allocated. The directory
track of a subdirectory is the first track in the partition, not
the middle one as for the root directory.

Clarification: The partition blocks are allocated from the parent
directory when a partition is made. The fullness of the subdirectory
does not change the 'blocks free' of the parent directory.
