[pstricks] node calculations

Several times, I have needed a macro which could be used as follows:
\midpoint{A1}{A2}{A3}
would label the midpoint of the line joining A1 and A2 as node A3.
It would be even better to have a macro which could be used as follows:
\interpolate{A1}{A2}{.7}{A3}
would label the point .3*Point(A1) + .7*Point(A2) with the lable A3.
Still better would be a macro so that
\linearcombination{1.2}{A1}{2.3}{A2}{A3}
would label the appropriate linear combination of the points labeled A1 and A2
with the label A3.
Has anyone has already figured out how to incorporate this into PSTricks? I assume that
raw Postscript code is required.
Thanks,
John Frampton
