[Gmsh] A parse error

[Ruth V. Sabariego]

Hi,
I've corrected your Extrude command.
Besides, you should split your arc in two.
See below.
Greetings,
Ruth

lc=0.2;
Point(1)={0,-1,0,lc};
Point(2)={1,0,0,lc};
Point(3)={0,1,0,lc};
Point(4)={0,0,0,lc};

Circle(1)={1,4,2};
Circle(2)={2,4,3};

Line(3)={1,3};
Line Loop(1)={1,2,-3};
Plane Surface(1)={1};

Extrude {{0,1,0},{0,0,0},Pi/2} {
  Surface{1};
}
