executed instructions not present our Amdahl. Amdahl responded b
In early discussions of this facility at SHARE, several customers owned up to

announced, so not likely available just yet. I only remember being impressed
with the clever workaround that kept the Amdahl useful.

MVCIN was indeed a useful instruction. I encountered it (IIRC) on a 4381. I
