Hi Mike,

the max. rank is a ./configure option in GNU APL. See

    ./configure  --help

I notice the maximum rank of an object in GNU APL is 8. 

In APL2, it is 63.

The most common APL FFT algorithm reshapes the input into a hypercube with dimensions of length 2, and makes a pass, operating on successive axes.  So if you want people to be able to do FFTs on vectors longer than 256 elements, a somewhat larger limit here would seem to be appropriate.

Just a suggestion...
