I possibly find the error   
   it is one function sys   
   compile as INT->Any   
      
   Here happen something as this   
      
   f(a)==(a=3=>3333;a=1=>"float";"Er")   
      
   In instruction:   
      
   > v:=f(1);[(v="float")@Boolean,v]   
      
   return   
      
   [false, "float"]   
      
   So the v would have the type Any and not String   
      
   Instead if:   
      
   f(a)==(a=3=>"3333";a=1=>"float";"Er")   
      
   The sys compile it as PI->String   
   and the result of   
      
   > v:=f(1);[(v="float")@Boolean,v]   
      
   Is   
      
   [true, "float"]
