Is there a way to program sound in Delphi in a manner similar to the Pascal line: "sound(frequency)" followed by
"nosound"  ?? I do not want to use *.wav type files.

Yep, there is :

Found them some time ago on the net,

Making PC Speaker Sound


Below are the procedures Sound, NoSound, and Delay. They are called in
the same way that Turbo Pascal's Sound, NoSound, and Delay procedures are
called. For example, to produce a 600 Hz tone for 200 milliseconds, you
would call the procedures as follows:

   Sound(600);
   Delay(200);
   NoSound;

procedure TForm1.NoSound;
begin
   Port[$61] := Port[$61] and $FC;
end;


procedure TForm1.Sound(Freq : Word);
var
   B : Byte;
begin
   if Freq > 18 then
      begin
         Freq := Word(1193181 div LongInt(Freq));

         B := Port[$61];

         if (B and 3) = 0 then
            begin
               Port[$61] := B or 3;
               Port[$43] := $B6;
            end;

         Port[$42] := Byte(Freq);
         Port[$42] := Byte(Freq shr 8);
      end;
end;


procedure TForm1.Delay(MSecs : Integer);
var
   FirstTickCount : LongInt;
begin
   FirstTickCount:=GetTickCount;
   repeat
      Application.ProcessMessages; {allowing access to other controls,
                                    etc.}
   until ((GetTickCount-FirstTickCount) >= LongInt(MSecs));
end;
