I believe I used it in DStar to save the current game.
Anyway, lets say I wanted to have an 8x8 game matrix and the levels were
stored at level_data. I could do:
....
 ld bc,(current_level-1)
 ld hl,level_data-64
 ld de,64
selectLevel:
 add hl,de
 djnz selectLevel
 ld bc,64
 ld de,matrix
 ldir
....
matrix:
 .ds 64

Of course this would be stupid since I could just use a safe ram area rather
than wasting 64 bytes of the calculators memory, but just an example...
