Thank you both for your help! In regards to JD's saving the output
arrays with pointers... I have never used pointers and believe this is
a case in which they are necessary.

After writing a long, drawn out explanation of where I was stuck with
pointers I ended up figuring them out. Just in case anyone new to
pointers wants to know how to get variables from an example such as the
above threads, use something like this:

x= ptrarr(3)

for i = 1L, n_elements(h) - 1L do begin
t=ri[ri[i]:ri[i+1]-1]
x[i] = PTR_NEW( t,/allocate_heap )
endfor

print,*x(2)

and you will have your varying size arrays of a larger array segmented
into different subscripts of x.

I'm sure there may be a better way to do this, but it makes sense to me.
