Isn't it odd . . .
. . . that a WebAssist binding tutorial, a WebAssist .js file, and a WebAssist snippet collection should have differing field names? The function of tutorials would seem to be one of enlightenment through "correct" examples that would be roadmaps for success . . .
But, paying attention is my job ultimately, so . . .
Thanks, CraigR, for sticking with this quest - I'm sure that there are more pitfalls that I will fail to navigate . . .
Thanks for the clue, I'm eager to see where it leads!
