the ldir command (which stands for load, decrement, increment, and repeat)
is used to copy large amounts of data from one place to the other.  It loads
bc bytes from (hl) to (de)...For example:

    ld    hl,level1
    ld    de,8265h
    ld    bc,100
    ldir
level:
... (level data)


that would load 100 bytes from level to 8265h (aka safescreen on the 83)
