Ah, I see, Mmmmm, well, one of my ideas would be mapping every known variable in C2 to a number, set the current number when the textbox finishes readimg and run an every tick loop that writes a variable to the text depending on that current number.
I'll tell ya, it's not worth the hassle, if you want a debug console, insert the browser object, run your project in chrome, and ctrl+shift+j to open web console and anytime you do Browser->Log, text is logged in it, it could be a variable, a string or both (with &), you can even log in a loop but that might slow down your app so do it only in debugging
Also, do Whiteclaws, if you want more help
