  45     NOTES
  46             This function is not called by apps directly. Instead dos.library/DosGet-
  47         LocalizedString is patched to use this function. This means, that the
  48         LocaleBase parameter above actually points to UtilityBase, so we make use of
  49         the global LocaleBase variable. This function is marked as private,
  50         thus the headers generator won't mind the different basename in the header.
