If my verb A is in negative, like けなくて, would it mean that one -must- go?

Oh! I didn't know that there was! Sorry for the trouble Michael. I'll transfer my sentence there.

Thank you!

I cannot find a separate grammar point about "だめ" (てはだめ), it's only vaguely mentioned here in a grammar note. As I understand it, it is used with similar meaning as this one. Can someone explain the difference to me if there is any?.

だめ isn't really a grammar point, it's a vocabulary term. ikenai is, literally, "it won't go", "it won't do"; something that won't work, that someone shouldn't do (or with a negative verb, something someone shouldn't NOT do.). だめ literally means "burdensome to the eye"; something that is of no use, if not troublesome, problematic. They overlap when referring to something that shouldn't be undertaken. kind of hits the same idea only stronger, as in "unthinkable" Hope this helps.
