You asserted that before, and I asked you to name a few computers from the
beginning of Fortran that had those capabilities.  I never saw a response.
Can you respond now?

What extracting, packing and unpacking?
	S3	S1<24
	S4	S2<24
	S5	S3*S4
and look: the 48 bit product of the 24 bit quantities in S1 and S2 is now
in S5.  (And what where your complaints about the syntax for assemblers?)
