The UNIX95 variable alters the way some commands behave. Generally it is not advisable setting this as an environmental variable but issuing it in a sub- shell or within a script, e.g.

(export UNIX95; ps -Hef)

will give a full listing but with shells and their subshells grouped together. It also allows you to control what the ps command displays, e.g.

  (export UNIX95; ps -o user,pid,sz,args)


(export UNIX95; ps -o user,pid,time,sz,args)

The UNIX95 variable can also effect vi, patch, the C compiler and various library calls. For details search the HP_online_documentation and search for UNIX95.
