Each shell has it's own copy of the workbench PATH structure. This allows each shell to be customized, but does lead to confusion because adding to the PATH in one shell does not affect the other shells. To change the PATH for the workbench and thus all new Shells you must use the NEWPATH option of the LOADWB command. For example, to add work:newdir to the PATH system wide you'd type:
>PATH work:newdir add >LOADWB NEWPATH
Now work:newdir will be added to the search path system wide.
