Routine Description:
  Refresh the global UpdateData structure.

Arguments:
  FormSetUpdate      - If TRUE, next variable is significant
  FormCallbackHandle - If not 0, will update FormSet with this info
  FormUpdate         - If TRUE, next variable is significant
  FormTitle          - If not 0, will update Form with this info
  DataCount          - The number of Data entries in this structure

Returns:
  None.
