Q:

Can "neither" be used with "nor"?

I have the phrase

You've entered neither a command nor a parameter.

Now I want to know is it correct or not? Can I use such combination as neither–nor in my case?

A:

Absolutely! You not only can, but should use the pair.In fact, this is the correct way of connecting two or more negative alternatives. 
For more examples, see here or definition 2.a here.
