Retrieve command line of process based on PID on SunOS 5.8 (Solaris 8)

Under linux I used to retrieve command line of process by reading thecmdlinefile in/proc/<pid> folder. I have not figured yet a way to retrieve the same info undersunOs 5.8.

`ps` can't really help due to the fact that most process (ksh scripts btw) are launched with full path and as such are too long for the limited description line of ps.

Any hint will be greatly appreciated.
