System.CommandLine for IDE debugging

In REALbasic I was able to set a System.CommandLine value in the IDE, for debugging purposes. I can’t figure out how to do that in XOJO. Is it possible?

It’s in the Shared Build Settings.

Okay, thanks. I have not yet gotten used to XOJO’s eccentricities – like showing you the Inspector from a right-click menu for most things, but not for Build settings. Never mind, I will get the hang of it eventually.
