Which is in essence what my program does, except it divides by 48
since I specified both the ptr and object name options.  It really
doesn't matter since neither of us provide room to materialize the
entries (which is when it slows down).

Two other differences:
 - I used the API wrapper instead of the MI builtin, because it will
work at all security levels (ala last Nov's discussion of this)
 - The count you get from MATCTX includes one per database file member
in addition to one per database file.  My code also got that count so
it could exclude it, making the count correspond better to what you'd
see from doing a DSPLIB command. 

Perhaps the latter is the same difference as the two counts your MI
shows.  My routine also runs in a fraction of a second, which the demo
program calculates and displays along with the object count.

As noted in the MI manual under MATCTX, this method is actually only
an approximation as it can be affected by a few factors.  But in my
experiments it was dead on in most cases, and real close in others.
