[J-learn] Session 7

[Arthur Anger]

Students--
After resting up from last night's contra dance and two sessions of shoveling
snow, then slush, I found that my primary error in yesterday's program
execution was having brought an earlier version of the script.  Attached is the
newer version, and a minor extension of "Aliases".

After loading Contras, run (from menu or by pasting) the last statement of the
script to display the execution record.
