**Re: launch() reference**

There recently was a question here about using launch() for a Processing sketch. The poster could not get it to work and I had trouble also: [https://discourse.processing.org/t/launch-function-does-not-work/37459/3](https://discourse.processing.org/t/launch-function-does-not-work/37459/3)

I wound up using _Runtime.getRuntime().exec();_ which did launch a Processing sketch. By any chance do you have a demo using launch() for this purpose?
