That is correct. For many demos, the results are shown in the browser's
developer console.

I tested, it compiles with pas2js trunk. We'll need to check the 1.4.8

I guess that you'll first need to acquaint yourself with web programming
before attempting to use pas2js, and in particular how to debug using the
browser. Even if you use TMS Web Compiler, that is a must.
