Extend the ADDENVVAR command with LEVEL(*SYS) to set the default for the machine.

System-level environment variables. The system-level environment variables are stored in a global environment space that is persistent across IPLs and is not associated to a particular job. They can be manipulated by using the Qp0zDltSysEnv(), Qp0zGetAllSysEnv(), Qp0zGetSysEnv(), and Qp0zPutSysEnv() APIs, as well as the CL commands ADDENVVAR, CHGENVVAR, RMVENVVAR, and WRKENVVAR. These variables exist until they are deleted. There is a limit of 4095 system-level environment variables.

Looks like it is by setting JAVA_HOME:

ADDENVVAR ENVVAR(JAVA_HOME)
VALUE('/QOpenSys/QIBM/ProdData/JavaVM/jdk70/64bit')

What's the right way to set the default Java version on V7R1? We have
several versions installed, and would like the default to be JDK7 64-bit.
