instruction was LH Rx,=H'4095' then the half word literal can be patched from 4095 to 4096. In the former case no simple patch is possible. In the latter case a simple patch is possible. It is also possible that, for whatever reason, the logic of a LA Rx,5 needs to be changed so that the value being put into the register is 4096 instead of 5.

Since you're taking hypothetical side trips, suppose that the 32767 needs to be changed to 32768 - you're no better of with LHI than with LA.
