Reading part of a file

I'm making a module system. I need to make the actual module then a form to go along with it. The only way I can think of doing this is makign a file and then sectioning the file so that the first part is read and put somewhere on a page them the other part is put on the same page later on or on a different page. How can this be done without reading a certain amount of characters? The actual module part won't all be the same length so...how can this be done?
