For the laboratory session, you should work with the xtango algorithm animations on fox.cs.vt.edu, with your .login file set to match that in fox. Issue the following commands:
cd /heath/envision/brueni/xtango/anims; xrdb -merge ../lib/xtangoathena.res; kmp; boyer after doing the proper setenv operation to enable display on your X device. Then you can repeat the two animations as desired. Use the sample pattern and text from your textbook, or others that you think of, and try the Run Animation button.
Note that there is another version of boyer and kmp in /u1/bin that is from a newer form of xtango.
