FUNCTION BUNGDROP()                              *new*

  Short:
  ------
  BUNGDROP() Causes dropdown during BUNGEE() menu def sequence

  Returns:
  --------
  NIL

  Syntax:
  -------
  BUNGDROP([nDown],[nOver])

  Description:
  ------------
  BUNGDROP() causes a dropdown to occur during a BUNGEE() menu
  definition sequence. This is followed by a series of BUNGOPTION()
  and then BUNGUNDROP() to end the dropdown.

  [nDown] Number of rows down from row of current option (default 1)
  [nOver] Number of columns over from column of current option
          (default is 0 for bar options, 1 for dropdown options)


  Use BUNGSTART(), BUNGEND(), BUNGOPTION(),
  BUNGDROP(), BUNGUNDROP() together to create a menu definition
  array for BUNGEE(). While it is not necessary to use these
  functions to create the array, it is helpful when you have
  a complex, multi-level dropdown structure.

  See BUNGEE for more information.

  Examples:
  ---------

  bungstart()

     bungoption("Files")
     bungdrop()
          bungoption("Open" ,{} ,{||!lFileIsOpen} )
          bungoption("Close",{||nil},{||lFileIsOpen } )
     bungundrop()
     bungoption("Edit")
     bungdrop()
          bungoption("DBF"  ,{||nil},nil )
          bungoption("Ascii",{||nil},nil )
     bungundrop()
     bungoption("Quit",{||bungeequit()},nil)

  aMenu := bungend()
  bungee(0,0,79,aMenu)
