Thanks to

	Chuck Kane	ckane@uiece.ece.uiuc.edu
	Dan Lanciani	ddl@harvard.*
	Doug McDonald	mcdonald@aries.scs.uiuc.edu
	John Birchfield	jb@altair.csustan.edu

for their quick answers to my problem.

One interesting note: none of them suggested using the FP_SEG
and FP_OFF macros (which were buried in the Run-Time Library
Reference).  Their solutions corrected my silly failure to
convert the segmented address into a 32-bit pointer.

Thanks again.  The net is always the fastest way to get an
answer.
