Yes it has some elements of APL since Ken Iverson is the father of both.

APL first, J subsequently.

However they are now appreciably different.

I would happily have stuck with APL if it were not that IBM sells its
version for quite a bit of money and also does not include with it decent
graphics, which I find quite irksome since a very nice and powerful package
was developed for APL at the TJ Watson Research Center around 1980 (!)
[RGRAF79] and used company wide for a number of yrs.

Now APL is sold mostly to financial analysts and statisticians, forget
engineers, this lowly crowd.

So I am learning J which has nice graphics and for the time being is
completely free.

Oh and BTW an IBM engineer got hold of one of Warren J Smith books and
implemented its contents in APL, graphics and all.

Nice but a little skimpy.

And now this program has rejoined others in this place in the sky where dead
programs end up.
It appears that it now has a new friend.
