Note the final "supplementary" problem (#20) on the Unit 5 homework, in which you are asked to implement a neat GUI for a previously-solved program. If anyone wants to tackle the "Learning Nim" program demonstrated in class, you can earn up to 10 points by converting it into a modern version that uses the mouse for inputting the # of matches desired, and visually displays the output in a JFrame of some sort.

For #2 on the Unit Five P+P you can assume that x is Sandwich, that y is a Sub and that both have been properly declared and initialized.

Please add the following line to the bottom of your .cshrc file (the dot is required):

source ~libs111/s111.cshrc

You may find that backspace doesn't seem to function properly in the jed text editor when using SecureCRT. Try using the delete key instead. Alternatively, you can download puTTY.

Assignment 2 has been released. Please read the Electronic Submission Guide before you get started.

Section Notes and Practice Exams have been added to the Lecture Materials section of the website.

Check the lecture materials page for the files you need for Unit 1. Also, since the .jkl file defines the location of the robot in the newspaper problem you may start with the robot anywhere you choose. The corner of 5th Street and 5th Avenue facing West is a popular choice.
