Greetings,

Is architecture level set (ALS) 1 required for OS/390 2.10?

What machine instructions are required for architecture
level set 1, as oppposed to ALS 0?  I seem to recall
that Perform Locked Operation (PLO) is ALS 1. What are the
others?

Is there a set of CVT flags for the ALS, or maybe there
are bits for individual instructions?

Also, is ALS 2 the 64-bit architecture?

Is there another ALS for the very recent instructions,
like Load And Test (LT) and Load Logical Immediate (LLILF)?

thanks in advance ;)
