These lessons are "generic" APL. Thus, many special features of the above APL interpreters (e.g. file systens) are not covered. If you are learning APL for the first time, get the user manual for your version of APL to learn about these features. Be sure to read/print HOWTORUN.TXT and FIX-THEM.TXT.
See workspace OUTLINE for a table of contents and a bird's eye view of the APL lessons. Use workspace KEYBOARD to learn the keyboard for APL's special symbols. See HOWTORUN.TXT for more instructions.
These lessons may be used for at-home study, by local APLSIGs to sponsor APL classes, or in a classroon. Whatever the setting, you will almost surely need the User Manual for your APL interpreter. Fortunately, user manuals, or commercial books, are free or affordable for most APLs.
