Or just redefine shortened to accept a pair!

patched but then also:
primarydef p
Thanks Aditya!
One can learn a lot with your answers !
In the Metafun manual I see enlonged but I did not know to use it.

Hi Aditya,
Thanks for the alternative method, which comes handy if one wishes to extend
the straight line by a different amount at either end:
\starttext
\startMPcode
z1 = (1cm,3cm) ;
z2 = (5cm, 9cm) ;
z3 = 1cm * dir(angle (z2 - z1)) shifted z2 ;
z4 = -.5cm*dir(angle(z2 - z1))

Or, if you want to use high school algebra:
\starttext
\startMPcode
z1 = (1cm,3cm) ;
z2 = (5cm, 9cm) ;
z3 = 1cm * dir(angle (z2 - z1)) shifted z2;
draw
Hi Fabrice,
Thanks a lot ! Indeed that does the job, which shows how wonderful Metafun is !

Hi,
I have a silly question: given two points in the plane
z1 = (1cm,3cm) ;
z2 = (5cm, 9cm) ;
the command
draw z1 -- z2 withpen pencircle scaled .5pt ;
draws the line segment joining z1 and z2. How could I draw the line segment
which goes a little further (say 1cm) than
