Great news,
Thank you Thomas.

Hey VIP folks

I am getting ready to start teaching in the spring an "Intro to AI" class and I wanted to include Prolog as one of the topics. Is the PIE still available?

P.

Rangarajan, While I haven't been using VIP 9 (yet!), in earlier releases of VIP, I was quite literally using a few thousand facts, reading (consult) and writing (save) them in a couple of my applications. In each case, these facts were spread across multiple different files. There was no noticeable ...

Thanks Thomas for that explanation. I was wondering about the same thing (but have been WAY too busy to start investigating.)

Jan, sorry for the delay in responding. Been off line. I have used both installers and simply copying from one device to another. As I mentioned, no registry modifications. The installers (2 different products) worked cleanly. Loved using them. The AV products simply did not like the application its...

Just a quick side note to this discussion. a few years back, an application I wrote worked fine and was approved to be on the network computers. It was used fairly extensively and was on the network for about 6 years. Then, with no warning, it was automatically stripped from all the computers. A wee...

Sorry, I've doing so much programming in c# lately I got confused.

my intent was correct though: 32 vs 64 natives.

not too sure, but have you tried making it convert to an 'int32' ?

I could be completely wrong but isn't == an equality comparison and = an assignment?

Why not use = ?

P.

how about inserting a simple test step at the beginning of the iteration for a key board entry if the Iteration count = a specific number? (it's the way I used to do debugging in VIP before there was a debugger).

Thomas,
The std::fromTo() 'sets' the next value of 'Y' from the sequence each time though, correct?

Michael, dumb question. I'm confused. Are you trying to restart the same foreach() loop from within the foreach() loop but with new start and stop numbers based on a action/decision within that loop? <clause>:- ... steps ... foreach(), %change the iterations of this loop and restart just the loop fr...

sorry, missed the implied cannot use recursion.

Deferring to Thomas.

I don't remember if it exists in VIP or not but how about a "while" loop instead of a foreach? pseudo code: Y = 1 While Y < 100, <do steps> < change value of Y (either increment by 1 or set to 100)> End While. in pseudo VIP: ... Y=1, MyWhileLoop(Y, Omega), % Omega is the upper limit) .... MyWhileLoo...

I am not an expert on the latest version of VIP (still need to upgrade from 7.5) but looking at your code block the logic looks iffy. (Assuming hierarchy_PART(...) and local_object(...) are fact bases) To see it, try re-ordering the clauses; add_local_conditionally(Module_name, In_local_list, In_loc...
