This thread has been curiously silent about one characteristic of routines/instructions executed above the bar. Unsurprisingly, they are measurably faster than their analogues executed below it. z/Architecture is 64-bit architecture
This is not, of course, their only or even their most important merit. Statesmanlike discussion of the relative merits of data spaces and memory objects is, at best, moot. The future, if there is one, is above the bar, for both data and executables.
