When a z/arch machine has CZAM installed, is it possible to use a short PSW
to IPL. Or, does the short PSW always become a long PSW before IPL, so it
is better to use a long PSW to start with?

In POPs, it says on page 3-75:

"When the CZAM facility is installed, the IPL PSW has the short-PSW format,
as shown in Figure 4-3 on page 4-8."

But on page 4-8, it says:

"Note: The term short PSW refers only to the eight-byte entity in storage.
The actual PSW used by the CPU is the 16-byte register illustrated in
Figure 4-2."
