==== Arguments ====
* '''const Bit[4]''' ''D'': Destination bank
* '''const Bit[4]''' ''S'': Source bank
* '''const UByte''' ''Dest'': Contains an operand of the bitwise OR and receives the result.
* '''const UByte''' ''Oper'': The second operand of the bitwise OR.
==== Description ====
Performs a bitwise OR operation between "Dest" and "Oper" and stores the result back into "Dest".
If the Source Bank is 0 then the “Oper†is the operand to OR with.
If the Source Bank is an 8 bit bank, then the “Oper†is the address in that bank where the operand is.
