So far, nothing is announced. It sounds to me like Steve was after some point in time where he could use extended immediate instructions. The answer is: it's not in the software but in the hardware. As you pointed out, if you are running a z9 or z10, the instructions are available, regardless of what release of z/OS you are running. You could use the TM instruction to see if the hardware has the feature. For example: tm 202,x'02' jo extend_imm_here * fall through, and extended immediate instructions are not available.

So, I have to drop those instructions until the O/S requires a hardware level that includes them. Thank you all for your quick replies.
