Re: st: Re: memory required for -merge-

Really, there's no "hopefully" about it. The place name contains few enough values and is short enough to fit in a value label. The revised dataset will only add about 3 bytes per observation (an int and a byte), so it will only require about 60MB of RAM which will easily fit within the 666MB remaining.
