Industrial Chemical Process Design

This chapter is dedicated to all of you who are committed and dedicated to good old General Working (GW) Basic. Like me, you don t want to change to this complex Windows Visual Basic (VB) [*]. I have written numerous programs in the old GW Basic and have produced very user-friendly input-output screens using special, commercially sold software packages. Unfortunately, this is all history and we now apply only VB in the Microsoft Windows environment.
For those of you who are not familiar with these historic Basic language programs, such as the most recent QuickBasic and the IBM Basic, may I affirm that you, too, have the same difficulty of applying the inputs and outputs of VB.
What can we do? Well, I first researched a number of Visual Basic books, finding few if any clear explanations of how you make the switch from the simple Basic of old to the new VB by Microsoft. I found that the books that came with VB 3.0 were the best guides. I then spent considerable time (several months) on many trials, learning and applying this VB. Well then, must we each spend this same time learning? I answer an emphatic no!
My recommendation is simply to follow the example I submit here. The real difference between this new VB and the old is simply the input and output screens with their respective input/output code differences. All the motors that run and produce your answers from your previous GW basic inputs are...
