Code Snippets
We have gathered a few snippets and example programs that may help you with writing
your own code. Each of these programs is available to view by clicking the
links and is also downloadable for you to modify and use for your own purposes.
If there isn’t a code snippet here that helps you we will be happy to
make suggestions on how to approach writing Venom code to solve any problem.
The single-file snippets will open as text files in your browser, but are best downloaded as Venom (*.vnm) files and viewed using VenomIDE2.
To view the zipped projects, click on the zip file to download it, right click and Extract all in Windows, and then double click the *.vpj file to view the project in VenomIDE2.
