There is a free version NARs-2000

Believe me- J is definitely faster, than this. I have had considerable
APL experience -sufficient to recognize that J has advantages
Admittedly, even for APL users, there is a learning curve- partly due to
the power of J and partly due to the indexing.
In APL +/ applied to a matrix will sum along rows but in J the
summation is along columns.
While APL has line numbers-their real use is in editing- rather than
"go-to's" where labels are more useful.
Use of -> foo vs ->3 (where 3 might change). Editing is actually easier
in J -using a script.
However where one has to go to different places as done by" if, else,
etc controls. I suggest that you
look up "control structures" in J. J also provides for labels as
targets for these statements (or other statements)
So what you had in APL is still available if needed-- plus more!

Hello:
I programmed APL in college.
Is there a free version out there?
I have J on my desktop, but can't get my head around no line numbers,
and gotos.
Yours, Bob.
