[comp.databases] Statistics with dBaseIV

I'm doing some basic descriptive statistics with a database
of survey results.

My question: how to quickly count fieldnames and so forth for specific
values.  My feeling is that "count for field_A=12 to memvar_A", "count
for field_B=26 to memvar_B", and so forth, would involve separate
"count"s for each variable in the database.  Obviously, the more
variables and records, the longer this will take.

Is there a better method for doing this?  Would it help if each field
counted were indexed?  Stuffed into an array?  (If so, how?)

Also, using dBaseIV 1.0, have you noticed that when you create an
input screen and limit the possible values allowed into a field (like
1, 3 and 7 as possible values), that the space of a one-digit field is
stretched out?  Why is this?  It produces much larger spaces than are
needed.
