NewRPL: Draw commands
Hello, it would be very interesting to incorporate drawing commands to motivate more users to use NewRPL.

For example

TI-Nspire: DrawArc 20, 20, 100, 100, 0, 90
NewRPL: 20 20 100 100 0 90 DrawArc

TI-Nspire:
xlist := {0, 200, 150, 0}
ylist := {10, 20,150, 10}
DrawPoly xlist, ylist

NewRPL:
{0, 200, 150, 0} 'xlist' STO
{10, 20, 150, 10} 'ylist' STO
xlist ylist DrawPoly

Another option is to adapt Python graphics syntax to RPL

PHP Code:
def modf(a,b):  return a-b*int(a/b)def rosace(n=12,r=31,v=True):  o=0.  ne=n+(n%2)  a=360/n  l=r*sin(a*pi/360)  for d in range(n):    if v:      avance  r      avance  -r      tourne_gauche  a/2      avance  r      avance  -r      tourne_gauche  -a/2    for k in range(ne):      avance  l      tourne_gauche a/(1+((n!=ne) and ((k==ne/2-1) or (k==ne-1))))    tourne_gauche adef demo(n):  efface   leve_crayon    avance  0  pas_de_cote  -3  baisse_crayon    rosace(n,32)

If you look the sources on Sourceforge you'll see that a sophisticated graphical library is in the making.

So, keep the faith!

...
ok

What would be the port to newRPL language of the previous code?
