Yeah, I made some use of SPX/IPX. Talk about a minefield! System data in user space, if your program crashed just ctrl-alt-del (this was back in the DOS era)

Yeah, I made some use of SPX/IPX. Talk about a minefield! System data in user space, if your program crashed just ctrl-alt-del (this was back in the DOS era) because the instant that data block got overwritten the system would crash anyway. On the other hand why hasn't anyone implemented a recycle bin like they did? (Your whole drive was your recycle bin.) And the users really loved the feature that said "this drawing is locked by <station name>" that I can see no way to implement under any other system.
