This is impossible to answer precisely without knowing what you mean
by "all at once."  Unless the record is very small (which wouldn't
seem to be the case, from your description), it almost certainly
is _not_ "all at once", in that several loads/stores will be
needed to accomplish assignment or comparison.

Perhaps if you explained more the nature of the "problem" you're
having, as well as the platform, compiler, and other details,
you'd be more likely to get meaningful help.
