I want to access the procNo in the main solver code. as follows：

if (ProcNo==0)
forAll(mesh.C(), pointI)
{
if ((mesh.C()[pointI].x()>0)&&(mesh.C()[pointI].x()<0.2))
{
in1[ii1] = pointI;
ii1++;
}
if ((mesh.C()[pointI].x()>0.2)&&(mesh.C()[pointI].x()<0.4))
{
in2[ii2] = pointI;
ii2++;
}
if ((mesh.C()[pointI].x()>0.4)&&(mesh.C()[pointI].x()<0.6))
{
in3[ii3] = pointI;
ii3++;
}
};

But when I wmake it and the error message is
error procNo is not declared in this scope

It should work with

if (Pstream::myProcNo() == 0)
{
...
}

or

if (Pstream::master())
{
...
}
