Is there a way to impliment non-determ predicates in foreign languages?

I imagine it would need some way of informing the foreign languages of Initial call, Redo call and Terminate call; or similar.

Thank you Thomas.
My project is x64. I think I get it - apart fom the <dll> example you gave, which looks the best solution for me. Please would you clarify the decalarion in the code and awhere/how the <dll> directory or the .lib file is added to the project.

I am trying to use a foreign DLL (rust in this case) I add the .lib file to the project. File Name: callrust\rustdll.dll.lib Name: rustdll.dll.lib Path: D:\VIP\rust_Direst\callrust\ When I build, the IDE seems to change the path by adding 64 to the subdirectory. fatal error lnk2506 : : Cannot open f...

Thomas,
Thank you. I know of the JSON class in PFC. It was RDF and OWL part that I was looking for.

I would like to experiment with OWL schemas and RDF schemas and triples etc.
Before I try building from scratch I though I would ask whether anyone either has a VIP package/library, or whether PDC plan on anything (in CE PFC) that might assist, perhaps JSON-LD RDF serialization.

When upgrading within a release: 1000ce to 1002ce, which says I have to deinstall before installing the 'upgrade'; should I also deregister and reregister?

I have used the comWrapper tool to create class and interfaces for an comDispInterface (automation) server. The wrapped classes have zero arity constructors. One of the classes returns an iDispatch object of the second class type. How do I create the class object from the iDispatch object? class DVD...

I am trying to use prodoc.exe to build documentation of the PIE project in the examples. The @filename, PIE10Doc.txt, contains: -2 -d "C:\Users\steph\Documents\Visual Prolog 10CE Examples\pie" -c *.png -r -o sab -e prodoc-err.log -v -db sab.dba -b sab\pie_cl.htm -y *.cl *.i and the result ...

I am sorry to ask such a basic question, but I have tied myself in knots over this. I would like to have an object that has a reference (pointer) to another object, not an embedded copy of the object. In fact a list of pointers to objects something like tuple(classname, objectref)* I probably haven'...

I am probably making a basic mistake, but I was hoping that the IDE would provide autocomplete popups with PFC classes etc. For example I add the Web/json package to the project and build. That adds in all of the required packages. In the editor in a .pro file I type in JSON = jsonObject:: and it do...

Thank you

HI,
coming back to VIP after many years Vip6CE.
I was wondering whether/how you can use a generated parser as a Scilexer for the edit control?
I would like to use a generated parser:

• Parse text in editor window with error reporting
  Colour/format text in window
  Both on opening a file and on a change
