Is there a way to disable the evaluation of an expression in a working page. For example:

x=1

y=2

z=x+y

I'd like to have y=2 not evaluated. Instead of deleting that line, is there a way that I can indicate to Maple to skip line 2? Many thanks.

       sin(4.5)=-.9775301177         I can NOT enter anything after ..177, the output.  Here = is ctrl+=.
