There are more ways of doing this and depend on thing such as if you know the sizes before hand and so on. So I'll offer one and might not just be the best for your case, but I hope it helps.

pa = ptrarr(4,/allocate_heap)
*pa[0]=long[25248]
*pa[1]=long[2905]
*pa[2]=long[4651]
*pa[3]=long[4988]

For i=0,3 do begin
;your work
print, mean(*pa[i])
endfor

If you know the sizes before hand, one other solution would be to make one array long as the 4 together and then subscript the array.

Cheers,
Helder
