>>-UUID--------------------------------------------------------><

The UUID generated by PL/I is a version 5 UUID per RFC 4122.

The name-space information consists of:

1. System information:
   • CPU count
   • MVS name
   • storage size
   • model and serial
2. Runtime 64 bit TOD value.
3. Job name or, if possible, the PID.

The UUID is a SHA1 hash of the above.
