Hello yes it opens a windows promp I guess. Like I said this is not the kind of stuff I do and am trying to learn it. I went to google a search for forums on shell scripting and this forum popped up so I came here for help. Am I in the wrong place?

XtPopup()																 XtPopup()

Name
  XtPopup - map a popup shell.

Synopsis
  void XtPopup(popup_shell, grab_kind)
	 Widget popup_shell;
	 XtGrabKind grab_kind;

Inputs
  popup_shell
	    Specifies a shell widget returned by XtCreatePopupShell().

  grab_kind Specifies how user events should be constrained.  (Can be one of XtGrabNone, XtGrabNonexclusive, XtGrabExclusive.)

Description
  XtPopup()  calls  the  functions registered on the shell's XtNpopupCallback list and pops up the shell widget (and its managed child).  The
  "Algorithm" section below explains this process in more detail.

  If grab_kind is XtGrabNone, the resulting popup is "modeless", and does not lock out input events to the rest of the application.  If it is
  XtGrabNonexclusive,  then  the resulting popup is "modal" and locks out input to the main application window, but not to other modal popups
  that are currently popped up.  If it is XtGrabExclusive, then the resulting popup is modal and locks out input to the main application win-
  dow and all previous popup windows.  For more details on XtGrabNonexclusive and XtGrabExclusive, see XtAddGrab().

Usage
  By  default,	XtPopup()  maps its window to the upper-left corner of the display.  You will generally want to position the shell by setting
  its XtNx and XtNy resources before calling XtPopup().

  The Intrinsics also provide convenience routines to popup a shell.  To perform a pop up from a callback list, register one of the functions
  XtCallbackNone(), XtCallbackNonexclusive(), or XtCallbackExclusive().  To do so from a translation table, use the XtMenuPopup action.

  Widgets can be popped down with XtPopdown(), the XtCallbackPopdown() callback function, or the XtMenuPopdown action.

  If  you  are	using the Motif widget set, you will generally never need to call XtPopup()   or XtPopdown().  The Motif XmDialogShell widget
  automatically pops up when its child is managed, and pops down when its child is unmanaged.

Algorithm
  The XtPopup() function performs the following:

  o  Calls XtCheckSubclass() to ensure popup_shell's class is a subclass of shellWidgetClass.

  o  Raises the window and returns if the shell's popped_up field is already True.

  o  Calls the callback procedures on the shell's XtNpopupCallback list, specifying a pointer to the value  of	grab_kind  as  the  call_data
     argument.

  o  Sets the shell popped_up field to True, the shell spring_loaded field to False, and the shell grab_kind field from grab_kind.

  o  If the shell's XtNcreatePopupChildProc resource is non-NULL, XtPopup() calls the specified procedure with popup_shell as the parameter.

  o  If grab_kind is either XtGrabNonexclusive or XtGrabExclusive, it calls:

	XtAddGrab(popup_shell, (grab_kind == XtGrabExclusive), False)

  o  Calls XtRealizeWidget() with popup_shell specified.

  o  Calls XMapRaised() with the window of popup_shell.

Structures
  The XtGrabKind type is defined as follows:

     typedef enum {XtGrabNone, XtGrabNonexclusive, XtGrabExclusive} XtGrabKind;
