I should have written

for (J=0;J<Next.length;++J){
F["B"+Next[J]].disabled = false;
}
DoSpecificTask[State](F);

This is not correct and comes up with "Next has no properties" on
answering the 4th question.

What would be the correct "vanilla" type iteration to replace your
following code?

for (J in Next) F["B"+Next[J]].disabled = false
DoSpecificTask[State](F)

You said, I think, that you have no such problem until you use
prototype.js; therefore, you should ask someone who knows that
prototype.js.

A Wikipedia search for prototype.js offers an amusing diversity of
articles.
