Martin, In the case of EXRX, in my example I used only OI instructions. However, I have a real-world example which uses a mixture of NI, OI, and XI instructions, so developing an immediate value and using one instruction is not an option.
Using BRUX or an equivalent technique is possible, but serves to enhance code bloat. I see far too much of that in Windows. I don't want to encourage it on the mainframe. John P.
