showing the full environment of a process in AIX

On a Solaris box you get the full environment of a running process by
using the command:

pargs -e

[ewer@sunray1:/>pargs -e 21437
21437:  ./cpubar.i386
envp[0]: UTDEVROOT=/tmp/SUNWut/sessions/15/unit
envp[1]: MANPATH=/usr/local/man:/opt/sfw/man:/usr/man:/usr/local/man:/opt/sfw/man:/usr/man:/usr/dt/man:/usr/man:/usr/openwin/share/m
an
envp[2]: SSH_AGENT_PID=11675
envp[3]: DTSOURCEPROFILE=true
...

On the AIX-System, the proc* commands do not have such an option.
Here the ps command can help to get the environment:

root@aixhaspa:/home/vswfl/tmp
# ps -ef | grep prog
