I have a question: are all variables global in PBP? Seems that they are and that that could get really confusing.
It also looks like there are a lot of reservered variables that add to the complication.
What has been you experience with this?
@Jeff M: They are all global. I don't have a problem with that in that I arrange them in a logical order and give them very descriptive names. I also don't "reuse" a variable for another purpose. That keeps the code clean and the logic on track.
In an age of globalization and rapid changes through scientific progress, two of our societies' (and economies') main concerns are to satisfy the needs and wishes of the individual and to save precious resources. Cloud computing caters to both of these.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
