Henrik,

Someone might have answered this already, but one of 
the simplest ways is to use Winexec.  As in:

   status :=
      Win32.Winbase.WinExec(lpCmdLine => To_Lpcstr("C:\MyDir\My.exe"),
                            uCmdShow  => Win32.Winuser.SW_HIDE);

This is superceded by the more complicated CreateProcess API, but
it will probably never go away, at least not for a long time.

John English also sent an example of another API which works as well.

  Win32.WinDef.HINSTANCE hInst :=
    Win32.ShellAPI.ShellExecute(
      System.Null_Address,                      -- no parent window
      To_LPCSTR("open" & ASCII.NUL),            -- command
      To_LPCSTR("c:\MyDir\My.exe" & ASCII.NUL), -- file to open
      System.Null_Address,                      -- no parameters
      System.Null_Address,                      -- no default directory
      Win32.WinUser.SW_SHOWNORMAL               -- show window normally
    );

Hope this helps.

Frank

how do I do that? does it exist any counterparts to "system" in perl or
something?

(I'm developing in win32 environment)
