Convert address to ASIC for absolute addressing...

Add 1 to the pointer in ahl, the next byte from the pointer in ahl is now
pointed to by ahl.

rst $20 = call _10toOP1 , loads 10 bytes from (hl) to OP1.

rst $10 = call _FIND_SYM, or something like that... , Takes input in OP1 and
finds variable with that same name.  pointer in bde, but it's simple to
switch it to ahl.
