The September/October issue of “Robot” contains a well researched review about ViewPort- tagline: “A deluxe Propeller debugger in a sophisticated development environment”.  Here some extracts:

The new ViewPort Development Studio from Parallax delivers an industrial-strength debugger combined with a Spin editor and a large set of powerful data-analysis views.  As a full-time software engineer working with Microsoft Visual Studio, I have been spoiled by sophisticated commercial development tools.  For me, ViewPort delivers the same power to my hobby as I have when I’m working at the office.  That isn’t saying that using ViewPort is like being at work; ViewPort is a lot more fun.

…

Most important, you can set breakpoints and single step your Spin program from this view.  This window is software engineer’s nirvana.

…

Let me assure you that, with very little effort, you’ll be able to make immediate use of ViewPort’s basic debugging feature.  To help you learn, ViewPort includes a great manual and many source-code samples and tutorials to help you master each capability.
