Indeed, that was a very old example which I had forgotten to include an `'='` character, which is required for the **runSketch()**'s `switch/case` block parser:

> <https://github.com/processing/processing4/blob/processing-1310-4.4.10/core/src/processing/core/PApplet.java#L9960-L9969>

So this is the fixed line:  
`final String[] switches = { ARGS_SKETCH_FOLDER + '=' + sketchPath(), "" };`
