The attached file does not print anything to the console when I hit the button. It works with invalue/outvalue but not the chnget/set opcodes. At least that's how it's behaving here. One other thing, I know it's purely cosmetic but do you think you could add a font and background colour option for the console window? I find t's nice to have a contrast between the editor window and the console output. Rory.
