sometimes it's beneficial to use all three fields though.

for instance, i have a program that i regularly run at 747k.
so that would (or could) be its _minimum_ size.
(i'd give it more memory if i could spare more, but i can't.)

however, with an allocation of 2 or 3 megs, the program
certainly would be less likely to run into memory problems.
so i would want to make that my _suggested_ size.

and today, where some machines have oodles of memory,
a _preferred_ setting of 4-5 megs might not be out of line,
especially for users skilled at finding my memory leaks.     :+)
