The reason for putting the "guts" of the program in a DLL written in
another language and using VB for the front end is primarily speed and
also versatility.

VB handles repeated calculations and loop very slowly when compared to
the same thing done in C or borland pascal.  For example, a routine I
did for generating fractals took almost 5 minutes on my 100dx to
finish.  By putting all the computations in a dll writting using BP
V7, I cut the time down to just over 2 minutes and this was without
doing any other optimizations.
