MOVES
Description: Moves the byte, word, or long operand from the specified general register to a location
within the address space specified by the destination function code (DFC) register; or moves the
byte, word, or long operand from a location within the address space specified by the source
function code (SFC) register to the specified general register.
If the destination is a data register, the source operand replaces the corresponding low-order bits
of the data register, depending on the size of the operation. If the destination is an address
register, the source operand is sign-extended to 32 bits and then loaded into the address
register.
