|No such thing as a small change|
What constitutes a framed web page are a frameset (an HTML page that outlines the location and layout of the frames) and the content that is filled in each frame. This layout allows you to load a new page (dynamic or static) and leave the other frames as-is.
If this method is okay for your purposes, might I suggest the following: assume you want a series of links on the left-hand-most side that will load something new in the right-hand side of the table.
View source to see how this is done, in case you're unsure of the HTML
Make each of the items a GET query to your perl program, and have it write back out the same table, but with the new content in the right side.
If you have any other questions, please feel free to ask!
