Sorry .. I nonchalantly use the word, but don't know precisely what it is.  I 
always kind of off-the-cuff figured it was memory I could use with DS or ES 
or SS (provided I pointed the right registers at it).  But that other things 
might be drawing on it also (e.g., alloc() and free() in C).
Hopefully someone else will come in here and explain it properly :-)
