That does work for a long time...:

gnuplot> set print "a.dat"
gnuplot> plot x
gnuplot> print 1,2
gnuplot> print GPVAL_X_MIN, GPVAL_X_MAX
gnuplot> set print
gnuplot> !cat a.dat
1 2
-10.0 10.0
!

Or do you mean sth completely different?

Piping is used in ginput.m, for example, to get MOUSE_ variables. For 
GPVAL_, it would be the same. The current gpinput.m is on gnuplot's web 
page.
