There is really no hard and fast "standard" regarding this, but there does
seem to be one particular way in which a significant number of people refer
to registers in BAL programs (IBM for one).  The R1-R15 designation seems
to be the most prevalent.  Certainly it the one I've seen used the most, and
the one which I have always used.
