and this is certainly true.   It is not, however, very interesting.  Base
registers retain their traditional usefulness for addressing blocks of
constants and, sometimes, DSECTs.  For almost all other purposes much better
constructs are now available and should be used instead.

About the use or non-use of SMP/E for maintaining ISV products, I would make
two points:

o ISVs that do not package and distribute their products using SMP/E are
retrograde and likely to
   be judged so, particularly by underqualified but sometimes influential
consultants who use check
   lists to evaluate program products; and

o In my now long experience I have never encountered a situation in which a
shop judged that a
   requirement that SMP/E be used to install and maintain an ISV or, a
fortiori, IBM product was
   disqualifying.

What we have here is, I think, an instance of what C. Wright Mills called
crackpot realism, the notion that clinging to the 'tried and true' is the
least problematic way to do business.
