AN OUTPUT LINE IS PROVIDED FOR EACH DIGIT PLACE OF THE SORUCE REGISTER. THE OUTPUT LINES ARE OFFSET A NUMBER OF DIGIT PLACES EQUAL TO THE LATERAL DISPLACEMENT BETWEEN THE SOURCE AND DESTINATION POSITIONS. THE OFFSET LINES ON BOTH SIDES OF THE DESTINATION POSITION ARE MASKED OFF AND THE REMAINING LINES, WHICH TRANSMIT THE TRANSFERRED DATA FIELD, ARE COUPLED TO THE DESTINATION REGISTER. A SPECIFIC APPLICATION OF THIS APPARATUS IS DISCLOSED IN WHICH A FIELD OF DATA IN A COMPUTER MEMORY TRANSVERSING ONE OR MORE CELL BOUNDARIES IS TRANSFERRED IN A HIGH SPEED OPERATION. ONE WORD AT A TIME OF THE SOURCE FIELD IS READ FROM THE COMPUTER MEMORY INTO THE SOURCE REGISTER. A PORTION OF THE WORD AT ONE BOUNDARY OF THE SOURCE FIELD IS TRANSFERRED TO THE POSITION OF A PORTION OF THE CELL IN THE DESTINATION FIELD. SIMILARLY, THE PORTIONS OF THE SOURCE FIELD FROM EACH WORD ARE IN TURN TRANSFERRED TO THE CELLS OF THE DESTINATION FIELD.
