What does PARI mean by "showing all possibilites"?

Question

I am running this code, unfortunately I have no idea that why it is asking me a yes or no question.

 Normu(D) = my(k = bnfinit(y^2-D, 1), u = bnfunits(k)[1][1]); nfeltnorm(k, u); 
  {
    L = List();
    forprime (q = 5, 100,
      if (q%8==5, 
        N2 = Normu(q);
        forprime(p = q+1, 100,
          if(p%8==5,
            N1 = Normu(2*p);
            N3 = Normu(2*p*q);
            istput(L, [[q,p], [N1, N2, N3]])))));
  }

Unfortunately I can not undrestand what PARI means by 'showing all possibilities'and asks me to type(y or n).

I tried to change commands, and change the default PARI size, but not successful. I know the problem is not in the function defined above. I appreciate your help.

Update: I wrote all the code in one line and it is working but it doesn't consider internal 'if's . It is not clear to me why it should work with this change.

    
 Normu(D) = my(k = bnfinit(y^2-D, 1), u = bnfunits(k)[1][1]); nfeltnorm(k, u); 
  {
    L = List();
    forprime (q = 5, 100, if (q%8==5, N2 = Normu(q);  forprime(p = q+1, 100, if(p%8==5, N1 = Normu(2*p); N3 = Normu(2*p*q); listput(L,[[q,p], [N1, N2, N3]])))));
  }
