Simplest solution is to use array for hash table. Size of array should has enough space for data entries and some amount of waste space for good performance.
Collision resolution mechanism also needed.
Look into CyrillicUtilities.Mod for inspiration (hashSearch procedure). The key in this hash is the array index.
