You can use this program however you see fit. If you have a question, do something cool with it, have an idea, want to make your own version, or find a bug, just email me (smartguy22129@yahoo.com). IMPORTANT: You need to run the setup program (hwsetup) first, otherwise you will get an undefined error. Keep it because you will need to run it again if your calc resets the archive memory Here are the keys to operate it: When in the first screen, use the six keys on the left (2nd, alpha, math, x^-1, x^2, and log) to enter detailed views of the subjects, or clear to go back to exit the program. It will take a while to do this because it has to archive the strings. Once in detailed view, press the key that got you there (one of the six) to return to the first screen. Press mode to write over the existing assignment, or put one in if there is not one already there. Press clear to erase it.
