I use something similar to Tonton's. (learned back in the VIP 4.x/5.x days and carried out to today)

I agree with the "awkward"

Stay consistent with the then as always part of the syntax.

before the for... capabilities were added to VIP (back when we only had to worry about Determ -NonDeterm and Succeed/Fail) I simply created my own predicate with a set of clauses that checked each condition and then executed <something>. There was almost always a 'graceful fail' at the end to go bac...

Thanks Martin, I couldn't remember the name "Halting Problem" - (they say memory is the 2nd thing to go when you get old, I just wish I could remember the 1st! )

very interesting question. Thomas may have another answer but in my gut, I think you might have a bunch of frivolous warnings. strictly playing devil's advocate here: What about the case where you are monitoring an external input, would that not be an endless loop? What about the case where the endl...

I had (still do actually) Turbo Prolog 2.0 When I upgraded to PDC 3 (many years ago), it was much easier to start over new rather than convert. The older code gave me design concepts and 'how' I wanted things to perform at the concept level but the effort to convert the code was too much and locked ...

back in the "old" days before the built in debugger, I used to do something very similar. I would create a global constant, then with conditional compilation flags, I would embed troubleshooting statements in my code surrounded by the flag. Then all I had to do was change the global flag's...

a few years back, based on advice from Thomas, Carston, and others from PDC while at the 2008 VIP-ALC in St Petersburg, I implemented my Neural Network in a Red-Black collection. It gave me faster performance and a clean structure. the NN was a multi-level one with many thousand neurons and many mor...

You're welcome.

Frank, I did something similar to what you are talking about approx. 20 years ago when I had to ensure that data values from user selections (e.g., radio buttons, specific text fields) being stored would always map back to the same control across all subsequent releases of the application. It was a ...

Thanks Martin, that makes sense.

curious, on the first call to floodStack(), it should have gone into an infinite loop, recursively calling itself until it eventually crashed.

I'm surprised it worked in the 32bit.

what are you referring to here "visual prolog with Machine Learning," neural networks? predictive expert systems that improve predictions as they learn? (I've done both) Look at PDC's home page. They've done "learning systems" a few times. Read the Proceedings of the two VIP-ALCs...

off the top of my head, here is one way to do this: (not tested and may not be 100% syntactically correct) constants low =1. mild = 2. high = 3. moderate = 4. Predicate tb_test(integer Weeks, integer WL, integer Fever, integer NS, integer LOA, integer Sputnum ...). Clauses tb_test(Weeks, high, high,...

remove the '.' from 7.x in your path, make it 7x

I seem to remember having problems with that in some programs when in XP, especially if there were more folders deeper in the tree.
