Why not just do something like:

int piece_of_data; /* I think `int' is correct, or at least should work */

/* ... */

piece_of_data = SPRITENAME; /* change for the appropriate sprite */
draw_sprite(doublebuffer, datafile[piece_of_data].dat, 16, 16);

Hope this is something similar to what you want.
