Data bounding operates on individual pieces of data versus data smoothing which has more effect on neighboring data points.. The program in the book was a combined bounding and smoothing program which I could not get to functionproperly.  I have included it (bsandd.bas), and if any of you mathematicians out there can figure it out, your help will be much appreciated.

Test case (data is embedded in program):

Data Bounding

Number of points to input? 20
Use keyboard (k) or read from data (d)? d

Data bounding

Result: Data bounded
