usec. maximum for 36 shifts) sir N Operation Code 676 This instruction will shift the contents of the In-Out Register right N positions, where N is octal digits 7-11 of the instruction word. _Shift In-Out Register Left_ (13 usec. maximum for 36 shifts) sil N Operation Code 666 This instruction will shift the contents of the In-Out Register left N positions, where N is octal digits 7-11 of the instruction word. _Rotate AC and IO Right_ (13 usec. maximum for 36 shifts) rcr N Operation Code 673 This instruction will rotate the bits of the combined register right in a single ring N positions, where N is octal digits 7-11 of the instruction word. _Rotate AC and IO Left_ (13 usec. maximum for 36 shifts) rcl N Operation Code 663 This instruction will rotate the bits of the combined register left in a single ring N position, where N is octal digits 7-11 of the instruction word. _Shift AC and IO Right_ (13 usec. maximum for 36 shifts) scr N Operation Code 677 This instruction will shift the contents of the combined register right N positions, where N is octal digits 7-11 of the instruction word. _Shift AC and IO Left_ (13 usec. maximum for 36 shifts) scl N Operation Code 667 This instruction will shift the contents of the combined registers left N positions, where N is octal digits 7-11 of the instruction word. * * * * * _Skip Group_ (5 usec.) skp Y Operation Code 64 This group of instructions senses the state of various flip-flops and switches in the machine. It does not require any reference to memory. The address portion of the instruction selects the particular function to be sensed. All members of this group have the same operation code. _Skip on ZERO Accumulator_ (5 usec.) sza Address 100 If the Accumulator is equal to plus ZERO (all bits are ZERO) the Program Counter is advanced one extra position and the next instruction in the sequence is skipped. _Skip on Plus Accumulator_ (5 usec.) spa Address 200 If the sign bit of the Accumulator is ZERO, the Program Counter is advanced one extra position and the next instruction in the sequence is skipped. _Skip on Minus Accumulator_ (5 usec.) sma Address 400 If the sign bit of the Accumulator is ONE, the Program Counter is advanced one extra position and the next instruction in the sequence is skipped. _Skip on ZERO Overflow_ (5 usec.) szo Address
