Using non-blocking assignments for combincational logic

In reply to dave_59:

Thank you, Dave. I am sorry, I didn’t remember that I had asked this question before. I guess the subject still has obscurities for me.

Also according to the LRM, variables that you make assignments to are not put into the senstivity list to re-trigger if you also plan on reading them in the same block.

Would you please elaborate this with an example so that I can understand it better? Or maybe refer me to the part of the LRM that explains this?
