At present, I expect little benefits for 64 bit build for the gnuplot.  
Octave for windows on 64 bit build has a benefit to treat large size data.
Before I challenge the octave build I have tried 64 bit build on the gnuplot.

Another point: Window 7 64 bit is now implemented even on $400 PC.
Applications will move to 64 bit in the future as win16 was replaced by win32.

Thank you for your variable suggestions. I will try them later.
