{
not a very elegant way of doing it but it should work
}
program nestedif ;

var
     name : array[1 .. 3] of string ;

begin
     {
          get the three names -- we could us a loop here
     }
     write ('Enter first name  ') ;
     readln (name[1]) ;

     readln (name[2]) ;

     readln (name[3]) ;

     writeln (name[1]) ;
     writeln (name[2]) ;
     writeln (name[3]) ;
     {
          sort and print
     }
     if (name[1] <= name[2]) and (name[1] <= name[3]) then begin
          {
               name[1] is first
          }
          writeln (name[1]) ;
          if name[2] <= name[3] then begin
