Hello,

Updates…

I did some testing on Windows 10 Pro and added comments to sketch below:

```auto
// This will launch a Processing 4.0b8 sketch when run on Processing 3.5.4 or 4.0b8:
//launch("D:/Program_Portable/processing-4.0b8/processing-java --sketch=/Users/me/Documents/Processing4b8/Grid_diagonals_1_0_2 --run");

// This will launch a Processing 3.5.4 sketch when run on Processing 3.5.4 or 4.0b8:
//launch("D:/Program_Portable/processing-3.5.4/processing-java --sketch=/Users/me/Documents/Processing4b8/Grid_diagonals_1_0_2 --run");

// Only Processing 4.0b8 is in my Windows path!

// Below is of interest:
// if run from Processing 3.5.4 it opens a 3.5.4 sketch
// if run from Processing 4.0b8 it opens a 4.0b8 sketch

// Processing 4.0b8 folder added to Windows path:
launch("processing-java --sketch=/Users/me/Documents/Processing4b8/Grid_diagonals_1_0_2 --run");

```

You will have to change paths and sketch names to run on your system.
