274 # If POSTDEFAULT is empty, no post update is performed.
276 # If both INVALID_P and POSTDEFAULT are non-empty then
277 # INVALID_P will be used to determine if MEMBER should be
278 # changed to POSTDEFAULT.
280 # If a non-empty POSTDEFAULT and a zero INVALID_P are
281 # specified, POSTDEFAULT will be used as the default for the

296 # that value. If POSTDEFAULT is empty then internal_error()
299 # If INVALID_P is empty, a check that MEMBER is no longer
300 # equal to PREDEFAULT is used.
