[Gmsh] subloops

[hubrys at virgilio.it]

Hi, when I run the file .geo, in message console appeare this message:

Info    : Reading '/home/alessandro/Scrivania/structure.geo'
Info    : 
Starting subloop 1 in Line Loop 21 (are you sure about this?)
Info    : 
Starting subloop 2 in Line Loop 21 (are you sure about this?)
Info    : 
Starting subloop 3 in Line Loop 21 (are you sure about this?)
Info    : 
Starting subloop 4 in Line Loop 21 (are you sure about this?)

Where is 
the error? Or isn't an error?

This is my file .geo:

Function 
Structure

  a2=newp;  
Point(a2) = {a+r,b+3*r,0,lc1};

  a3=newp;  Point(a3) = {a+2*r,b+2*r,0,
lc1};

  a4=newp;  Point(a4) = {a+r,b+r,0,lc1};

  a5=newp;  Point(a5) 
= {a+r,b+2*r,0,lc1};


  c1=newl;  Circle(c1) = {a1,a5,a2};

  
c2=newl;  Circle(c2) = {a2,a5,a3};

  c3=newl;  Circle(c3) = {a3,a5,
a4};

  c4=newl;  Circle(c4) = {a4,a5,a1};



circle_loop[] += {c1,c2,
c3,c4};


Return

Thank for your help
