Welcome Joseph!
Being an old programmer I became fascinated by J.
There is a lot to learn, but some of it is unnecessary to the beginner.
The 3 operations, addition (+), multiplication (*), and exponentiation (^), are
sufficient for many computations. Having sign change (-) you do not need
subtraction (b-a)=(b+-a), and division (b%a)=(*/(b,a)^1,-1), nor (%a)=(a^-1),
(%:a)=(a^2^-1), (+:a)=(a*2), (-:a)=(a*2^-1), (-.a)=(1+-a), (>:a)=(1+a),
(*:a)=(a^2).
Note that expressions are evaluated from right to left: (a^b^c)=(a^(b^c))
Have fun!
Bo.

Hello all,
I am a novice programmer and was looking for a language to learn for fun. I
tried APL but I couldn't get the keybindings to work on my computer. I then
found J from reddit and some google fu. It looks like an awesome language,
and i can't wait to learn more and make some fun programs. I'd thought i'd
pop in and say hello, so hi!
regards,
Joseph TUrco
