Memory access

Memory access in this mod occurs over digilines, with the channel as the prefix plus the memory address, and the message as either the new value or 'get' to get it returned, so for example:

Prefix Address Value Channel Message
A 1 4 A1 4
Default 15 get DefaultF get

4090 suptract TOS sub
4089 jump to TOS jmp
4088 skip if TOS = zero sez
