As with a huge number of things, the best thing for any "owner" is to use a 3-character prefix that they own. This is necessary for avoiding conflicts, whether in part names, messages, name/token names, data space names, ENQ qnames/rnames, etc.
I'm not sure how a customer's Share installation code fits into that scheme. We probably all have heard of the general situation that IBM "owns" names beginning A through I and SYS. There are some exceptions (mostly due to "grandfathering"). Going forward, any future IBM-created system symbol(s) would begin with SYS (at least as long as I'm involved), unless (perhaps) the symbol is created conditionally under control of some (non-default) customer-specified option. For example, if we ever make the LPAR name into a system symbol, it won't be &LPARNAME.
