     GetExtent(R);
     R.A.Y := R.B.Y - 1;
     StatusLine := New(PStatusLine, Init(R,
       NewStatusDef(0, $FFFF,
         NewStatusKey('~Alt-X~ Exit', kbAltX, cmQuit,
         NewStatusKey('~F1~ Help', kbF1, cmHelp, nil))),
       nil)
     );
   end;
                   

2. Inline Assembly:

   Turbo Pascal allows embedding x86 assembly code for performance-critical sections.

   function AddAsm(A, B: Integer): Integer;
   begin
     asm
       MOV AX, A
       ADD AX, B
     end;
   end;
                   

3. Units and Libraries:

   Creating and using external units for code organization and reuse.

   unit MyMath;
