The EVAL program I just created may or may not be of interest to you, but I would like to present a possibly neat way of using "dynamic" menus on the HP-41. The menu (top row of labels) changes depending on the context to make better use of the top labels and make the program more user friendly.
The program itself makes it easy to make a requirement specification and then pitch cases against that specification to get a total score of how well a case fits the bill.
