==== Arguments ====
* '''const Bit[4]''' ''D'': Destination bank
* '''const Bit[4]''' ''S'': Source bank
* '''const UByte''' ''Dest'': The destination variable, to which the operand is subtracted.
* '''const UByte''' ''Oper'': The operand to be subtracted from the destination.

==== Description ====
Subtracts "Oper" from "Dest" and stores the result back into "Dest". The result of the subtraction is capped at 0.
If the Source Bank is 0 then the â€œOperâ€ is subtracted from the destination value.
If the Source Bank is an 8 bit bank, then the â€œOperâ€ is the address in that bank where the operand is.
