The test register: The address of the binary register that contains thedata to compare.L T. The compare register: The address of the binary register that containsthe compare data.fJ GT. The compare register: The address of the binary register that containsthe compare data.LT. The test register: The address of the binary register that contains thedata to compare.IJ Branch instruction: The number minus 1 of the 4-byte object code instructionsfrom the next sequential instruction to skip if the branch is taken (±128object code instructions from the next instruction). If bit 23 is 1, the numberis a negative displacement in twos complement form.The branch is taken if:• The content of the test register is greater than the compare data and GT isspecified.• The content of the test register is less than the compare data and L T is specified.Object Code I~struction Format 231
