C08C: 0F 29        CLR $29      Set $2029 = 0
C08E: 0F 2A        CLR $2A      Set $202A = 0

Here's our first instance of direct addressing; since we already set the offset to 0x2000, the CLR $39 actually means CLR$2039. I presume one or two variables will be stored here, though we don't yet know what they are.
