This is a much better way of doing it for sure.  No uncontrolled alignment
or size problems. I'll have to move on in the book because Union are coming
up.

Thx guys
It's been entertaining to say the least!

As far as "equate".  It's been awhile.  Just know I did it in Fortran with
great results about 20 yrs ago. In fact I don't even have the books or
software anymore.

The %LX deal works, but I can see that size and alignment are issues which
may be hard to nail down and control from the programmer side of the
compiler

The comment about the float being passed as a double seems to be upheld in
one of my experiments.  Where 1.0 = 0x3FF0,0000,0000,0000 in float or double
variables.  And when using different values the number did track correctly
(as doubles).
