Spooky timing!! I was just researching the PCCA as we got burned in z/OS 1.12 as the PCCA pointer in the PSA is now 31 bit address and one of our home grown utilities failed.
The 1.12 data areas books still say that the following fields are part of the programming interface: PCCACAFM PCCACPID PCCACPUA PCCASLIH PCCASTPI TOKEN we use PCCACPID to find out the machine we are running on. Not bothered about which CP!
