(which is interesting to see for me,
 if I had known that my posted functions would make it to an APL
 BTW: Does one need special plugins / fonts to properly view
     the APL symbols ? )

well, I've learned about J as the ASCII-variant of APL, and APL
used to be my first `beloved' computer language (in high school!)
-- but does J really provide computer algebra in the sense of
Maxima , Maple or yacas... ??

(and no, please refrain from flame wars about APL vs .. vs ..,
 it's hard to refrain for me, too...)
