Next is the statement to define your Order browse:

DEFINE BROWSE OrderBrowse
  QUERY OrderBrowse NO-LOCK DISPLAY
      Order.OrderNum FORMAT "zzzzzzzzz9":U
      Order.OrderDate FORMAT "99/99/99":U
      Order.PromiseDate FORMAT "99/99/99":U
      Order.ShipDate FORMAT "99/99/9999":U
      Order.PO FORMAT "x(20)":U WIDTH 19
    WITH NO-ROW-MARKERS SEPARATORS SIZE 65 BY 6.67 ROW-HEIGHT-CHARS .57 FIT-LAST-COLUMN.

This code first names the query the browse is defined for, and then the list of fields to display, along with their formats. Finally there is a list of attributes for the browse itself, in a phrase starting with the keyword WITH. You can set these and other attributes in the Browse property sheet you looked at in Use property sheets.
