Some years ago, on our z800 processor, we measured the performance of (in-place) TR against a software-coded loop. We found that the loop was faster than TR for strings shorter than nine (9) bytes in length. When we spoke to IBM about this, we learned that TR had been partially moved into millicode for the [...]

for expensive, specialized HVAC systems to support the mainframe evaporated, greatly
reducing the overall costs. In the mid-’90s, the [...]
