+files - basic file handling commands
+editor - text editor; must know about files first.
+morefiles - more on file manipulations and other useful stuff
+macros - "-ms" macros for BTL memos & papers;  must know editor
+eqn - typing mathematics;  must know editor
+C - writing programs in the C language;  must know editor
+
+This is probably the proper order, but after you
+have the "files" course and know the basics of "editor",
+try anything you like.
+
+You can always leave learn by typing "bye" (and a RETURN).
+You can stop it from typing by pushing interrupt
+(or break or rubout or delete, depending on your terminal).
+
+If it won't accept your answer, and you know\b\b\b\b____ you're
+right, answer "no" when it asks whether you
+want to try again, and it will go on to the next lesson.
+Please report troubles to your local guru, or
