如何控制程序的执行？

[llanero]

现有DELPHI编写的一个程序，没有窗口显示，在WIN的命令行方式下执行，程序的处理没有完成，就返回到命令行的状态。请问各位大虾：有没有办法让程序执行完后再返回命令行状态？

function WinExecAndWait32(FileName:String; Visibility : integer):dword;
var
zAppName:array[0..512] of char;
zCurDir:array[0..255] of char;
WorkDir:String;
StartupInfo:TStartupInfo;
ProcessInfo:TProcessInformation;
begin
StrPCopy(zAppName,filename);
GetDir(0,WorkDir);
StrPCopy(zCurDir,WorkDir);
FillChar(StartupInfo,Sizeof(StartupInfo),#0);
StartupInfo.cb := Sizeof(StartupInfo);
StartupInfo.dwFlags := STARTF_USESHOWWINDOW;
StartupInfo.wShowWindow := visibility;
if not CreateProcess(nil,
zAppName, { pointer to command line string }
nil, { pointer to process security attributes }
nil, { pointer to thread security attributes }
false, { handle inheritance flag }
CREATE_NEW_CONSOLE or { creation flags } NORMAL_PRIORITY_CLASS,
nil, { pointer to new environment block }
nil, { pointer to current directory name }
StartupInfo, { pointer to STARTUPINFO }
ProcessInfo) then Result :=0 else begin
WaitforSingleObject(ProcessInfo.hProcess,INFINITE);
GetExitCodeProcess(ProcessInfo.hProcess,Result);
end;
end;
