为了更好地理解，我正在探索 HLA 教程的示例。我试图组装并运行它，但未能获得输出。在我组装之后，它向我显示了这个错误：
Error in file "001_HelloWorld.hla" at line 87 [errid:39120/hlaparse.bsn]
Parameter list is missing "raiseAdrs" found in fwd/extern definition.

这是示例程序的完整代码：
program helloworld;
#linker( "comdlg32.lib" )
#linker( "comctl32.lib" )
?compileAll := true;
?@NoDisplay := true;
?@NoStackAlign := true;
#includeOnce( "stdlib.hhf" )
#includeOnce( "howl.hhf" )
const
applicationName := "Hello World";
formX := w.CW_USEDEFAULT; // Let Windows position this guy
formY := w.CW_USEDEFAULT;
formW := 600;
formH := 600;
static
align( 4 );
bkgBrush_g :dword;
bkgColor_g :dword;
// Form declaration.
// We've got an empty form with no widgets, so this is fairly trivial:
wForm( mainAppWindow );
endwForm
// Must include the following macro invocation to emit the code that the
// wForm macro generated:
mainAppWindow_implementation();
// The following gets called immediately after the main application
// window is created. It must be provided, even if it does nothing.
method mainAppWindow_t.onCreate;
begin onCreate;
end onCreate;
///////////////////////////////////////////////////////////////////////////// //

//
// The following is mostly boilerplate code for all apps (about the only thing
// you would change is the size of the main app's form)
//
//
///////////////////////////////////////////////////////////////////////////// //
//
// When the main application window closes, we need to terminate the
// application. This overridden method handles that situation. Notice the
// override declaration for onClose in the wForm declaration given earlier.
// Without that, mainAppWindow_t would default to using the wVisual_t.onClose
// method (which does nothing).
method mainAppWindow_t.onClose;
begin onClose;
// Tell the winmain main program that it's time to terminate.
// Note that this message will (ultimately) cause the appTerminate
// procedure to be called.
w.PostQuitMessage( 0 );
end onClose;
// When the application begins execution, the following procedure
// is called. This procedure must create the main
// application window in order to kick off the execution of the
// GUI application:
procedure appStart;
begin appStart;
push( esi );
// Create the main application window:
w.GetSysColor( w.COLOR_MENU );
mov( eax, bkgColor_g );
w.CreateSolidBrush( eax );
mov( eax, bkgBrush_g );
mainAppWindow.create_mainAppWindow
(
applicationName, // Window title
w.WS_EX_CONTROLPARENT, // Need this to support TAB control selection
w.WS_OVERLAPPEDWINDOW, // Style
NULL, // No parent window
formX, // x-coordinate for window.
formY, // y-coordinate for window.
formW, // Width
formH, // Height
bkgColor_g, // Background color
true // Make visible on creation
);
mov( esi, pmainAppWindow ); // Save pointer to main window object.
pop( esi );
end appStart;
// appTerminate-
//
// Called when the application is quitting, giving the app a chance
// to clean up after itself.
//
// Note that this is called *after* the mainAppWindow_t.onClose method
// executes (indeed, mainAppWindow_t.onClose, by posting the quit message,
// is what actually causes the program to begin terminating, which leads
// to the execution of this procedure).
procedure appTerminate;
begin appTerminate;
// Clean up the main application's form.
// Note that this will recursively clean up all the widgets on the form.
mainAppWindow.destroy();
w.DeleteObject( bkgBrush_g );
end appTerminate;
// appException-
//
//
// Gives the application the opportunity to clean up before
// aborting when an unhandled exception comes along:
procedure appException( theException:dword in eax );
begin appException;
raise( eax );
end appException;
// The main program for a HOWL application must simply
// call the HowlMainApp procedure.
begin helloworld;
HowlMainApp();
end helloworld;
我尝试了我能解决的问题，但无法解决。
任何帮助将不胜感激，并提前感谢。
