How about store?  eg, if the RAM containing the two bytes initially
contained 2#0101010101010101# would it be permissible, do you think,
for  Rec.X := 7;  to result in  2#0101010101010111#  or
2#0101010100000111#?  And what if we are talking about memory mapped
IO, where an access is important, even if what is being stored is a
zero.
