Without an external security manager product such as RACF does zVM
provide any security services or controls such as logging for
administrator actions.

Our corporate standards require regular password changes, SMF like
logging, non-shared userids... and looking at the VM documentation it
doesn't look like native zVM provides these facilities, but please
correct me if I am incorrect.

The primary purpose of the DATA statement is to give names to
constants; instead of referring to pi as 3.141592653589793 at
every appearance, the variable PI can be given that value with
a DATA statement and used instead of the longer form of the constant.

This also simplifies modifying the program, should the value of
pi change.
