Question: How to hide input statements in document mode?

My last question was answered so quickly, I thought I would try again:-) I am developing documents for my class in document mode. I want to be able to set the examples up so that if they change the example, then maple will update all of the subsequent calculations connected to it. I think I have that pretty well figured out. My problem is that the flow of the document is interrupted by the necessary maple commands to produce the required output. For example, I have the code "subs(x=-4,(4.2.3))" that is executed to give an equation. It shows the code and then the equation on the next line. I would like to hide the code. I realize that if I right click on the expression and select 2d math, there is a hide expression command, but it does not work consistently. Sometimes it will hide the expression but leave blank space where the expression was, sometimes it will only hide a piece of the expression, and sometimes it will do nothing at all. I am sure (well, hoping really) that there is an easy, consistent way to do this. (Especially without leaving a blank space) Any help would be appreciated. I apologize in advance if this information is publicly available, but I have done a search without finding anything. S.M.
