I too have never used Proton before.

And all I can say is that there was a group of people here that used to be pretty good with PBP, who suddenly switched to Proton.
You'll now find those same people over at the Swordfish forum.

I would not recommend Swordfish for beginning programmers.

But if you're proficient in a language like Delphi (pascal), Javascript, or other "Highly Structured" languages, you might find Swordfish easier to work with.
