Are there any parameters I can use to supress pop-up HOST window when I call
HOST('copy file1, file2) from Oracle forms, or do it at the backend so it will be invisable for users.
Also, what is the handle condition to check status  on HOST command

1)You cannot suppress pop-up HOST window in GUI applications.
2)There is FORM_SUCCESS built-in there:

· On Microsoft Windows NT, when using HOST to execute a 16-bit application, the FORM_SUCCESS built-in will return TRUE whether the application succeeds or fails.  This is a Microsoft Win32 issue.  32-bit applications and OS commands will correctly return TRUE if executed sucessfully and FALSE if failed.  Invalid commands will return FALSE.

· On Windows 95 platforms the FORM_SUCCESS built-in will always return TRUE for HOST commands which fail.  This includes calls to command.com or OS functions, any 16-bit DOS or GUI application, or an invalid command.  32-bit applications will correctly return TRUE if executed sucessfully and FALSE if failed.

More you can read in the on-line help "HOST built-in" topic.

Like HENKA said, you may use built-in function FORM_SUCCESS to check the status of the HOST command.
But i would think that if you use HOST('copy x y',NO_SCREEN); with NO_SCREEN parameter, then the pop-up window would be suppressed.
