Constructing an array value from a sequence

I am looking for suggestions how to read and write
a value into an object containing sequences
at a particular array location given a sequence of integers.

For example:
   I have a sequence called  'my_data' which containing sequences
   within sequences.  The procedures  will
  read the value of a selected part of 'my_data' and
  write a value to that location.

Header of procedures:
  procedure Read_Data (sequence my_data, sequence data_location)
  procedure Write_Data (sequence my_data, sequence data_location)

Required criteria of 'my_data'
         The data object will not have a fixed record length, but rather
will contain
         variable size lists (within variable size lists):

For example if my_data equals:
 {{"dog",{"beagle","spaniel", {"shepherd",{"large","small"}}},
{"colors",{"black","white"}}}
then my_data[1][2][3] = {"shepherd",{"large","small"}}
and has a sequence representation of  {1,2,3}

my_data[1][2][3][1] is equal to  "large" (has the sequence value of
{1,2,3,1})

and my_data[2][2][3] would produce an out-of-bounds error message.

I have developed one method which will read the data given the sequence,
but none so far that will write the data.

Please do not suggest assembly code solutions.
