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?
http://www.ibm.com/servers/s390/os390/plug.html
Is there a set of CVT flags for the ALS, or maybe there
are bits for individual instructions?
CVTH7703 implies ALS 1 is present.
Also, is ALS 2 the 64-bit architecture?
No. http://www.ibm.com/servers/s390/os390/plug1.html
Is there another ALS for the very recent instructions,
like Load And Test (LT) and Load Logical Immediate (LLILF)?
No.
