A Windows gnuplot-specific problem: Looking for a general procedure to pipe or redirect a system response or data into a gnuplot variable

Show all headers | View raw

The subject line says it all; in recent posts in this group and on stackoverflow, I've asked about a way to pass system command-derived values or strings to gnuplot for use as labels, variables etc.  Posters sfeam here and mgilson on stackoverflow suggested a couple of simple ways to achieve that--but these methods invariably result in the hated 

gnuplot> a = "`tail -1 data.out | awk '{print $1}'`"                                            
         warning: system evaluation not supported by MS-Windows 32 bit

error message on my Windows XP platform despite the fact that I extensively and successfully use various U*X and GNU utilities in other contexts.

Thus my general question: what is the tested general way to pass a system-derived string or parameter to Windows (XP)-based gnuplot for use as a constant, label etc.?
