[Q] structure definition with variable array size [message #12101]

I wish to create a structure for holding a slice from a 3d volume along
with domain info, e.g.,

pro slice__define
tmp = {slice, data:fltarr(100,100), x:fltarr(100), y:fltarr(100), z:0.0}
end

This definition is fine if the data dimensions are known. However, what
if the array sizes are only known at runtime when the data file is opened
and brought into IDL. Is it possible to have structures with arbitrary
length arraysa la F90, C, or Pascal?

Cheers,
Darran.
