I would do something like this:

arrays = PtrArr(24)
FOR j=0,23 DO BEGIN
...calculation to obtain array of whatever size
arrays[j] = Ptr_New(thisLoopArray, /No_Copy)
ENDFOR

Now you have a pointer array. Each element in the array
is a pointer to another array of variable length.

array1 = *arrays[0]
array2 = *arrays[1]
...
array24 = *arrays[23]

Be sure to free your pointers when you are done with them:

Ptr_Free, arrays

Cheers,

David
