where # identifies the label number.
For ps_2_x, the label number must be between between 0 and 15.
For ps_2_sw, ps_3_0, and ps_3_sw, the label number must be between between 0 and 2047.
| Pixel shader versions | 1_1 | 1_2 | 1_3 | 1_4 | 2_0 | 2_x | 2_sw | 3_0 | 3_sw |

This instruction defines a label located at the next shader instruction. The label instruction can only be present directly after a ret instruction (which defines the end of the previous subroutine or main program).
