LETTERS TO S&C
In the August 1987 issue of Stocks & Commodities magazine (pages 42-45) you reviewed the software

I would like additional information on this program. Would you please send me their address and

Not so quick Quickbasic
I just received my Quickbasic 4.0 update. QB3.0 is fantastic. A great editor, unbelievable speed. On it my
optimization program takes 27 seconds (11 to compile, 16 to run). On QB4.0 that program takes 83
seconds! I average about 100 programs run every day. Losing 56 seconds on every run for 100 runs
would cost me about 1 hour 33 minutes every day. If speed is your #1 priority, as it is for me and most of
my friends, I would advise against ordering a QB4.0 update and for hunting up a QB3.0 if you buy a new
one. This is my first bad experience with Microsoft. QB4.0 must have new advantages that offset the loss
of speed for some people.
CHARLES M. LARSON
Yes, Quickbasic 4.0 does have new advantages. Whether or not they offset the loss of speed depends on
your application. QB4.0 uses the new IEEE standard floating point, which enables much higher precision.
Thus, while the number-crunching programs tend to drag their feet with QB4 .0, you will not likely
experience the sort of errors that could result from "loose" decimal rounding in QB3.0. With some
iterative programs, this improved accuracy can mean the difference between success, and failure in the
real world of trading -Ed.
