That's only the language, I strongly recommend using dedicated VS Code extension that supports graphical tools VS code extension: https://marketplace.visualstudio.com/items?itemName=verum.de... Verum Dezyne binary: https://verum.com/download/ It's a bit confusing but Dezyne - language, command-line version. Verum Dezyne - same + graphical tools

If you need a working example, you can find a simple Cmake/C++ implementation: https://forum.verum.com/t/automatic-lights-a-complex-system-...

If you are stubborn enough you can model even the smallest detail of logic in Dezyne and then use single lines of C++ hand-written code to manipulate IOs: https://bitbucket.org/j0ran/alarmsystem/src/alarmsystem-no-m...
