LIB("normal.lib");    
     
proc norExample2()
{
     ring r = 2,(x,y),dp;
     ideal I = x+1,y;
     // check that I is radical and prime:
     ASSUME(0, idealsEqual(I, primdecGTZ(I)[1][2]));     
     list nor = normalP(I, "withRing"); 
     def norTestResult   = norTest(I, nor); 
     print ("norTest: ([1,1,1] if ok!) ");
     norTestResult;     
}

norExample2();

output: 

. norExample2();
1
0
norTest: ([1,1,1] if ok!)
