The command IsBlockMarked() has four returns:
                _INCLUSIVE_
                _NONINCLUSIVE_
                _LINE_
                _COLUMN_
The meaning of _LINE_ and _COLUMN_ is clear.  But I can't find an
explanation of the meaning of _INCLUSIVE_ and _NONINCLUSIVE_.
Why do I care?  Well, in implementing TSE_CAL.S I found
that _LINE_ blocks cause it to lock up.  I solved my immediate
problem by changing line 115
from:
 If ((isBlockMarked() == FALSE)    // Be sure there is a Block
to:
 If ((isBlockMarked()==_COLUMN_)==FALSE) // Be sure there is a ColBlock
But in working out that solution I came across the _INCLUSIVE_ &
_NONINCLUSIVE_ block characteristics that I don't understand and can't
find an explanation for.
Guidance would be appreciated.
