==== 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 SWord''' ''Oper'': The operand to be subtracted from the destination.
==== Description ====
Subtracts two numbers and stores the result back into “Destâ€. The result of the subtraction wraps around into the 16-bit range.
If the Source Bank is 0 then the “Oper†is subtracted from the destination value.
If the Source Bank is an 16 bit bank, then the “Oper†is the address in that bank where the operand is.
