The
lower_cmc1 and
upper_cmc1 arguments are numeric expressions generally representing the date of birth CMC range. The
lower_cmc2 argument is not used (but is used by
adjlba). The
upper_cmc2 argument is a numeric expression of the CMC of an event, generally the date of an interview. The
age argument is a numeric expression expressing the age of the person in complete years.
The function returns the adjusted upper bound of the CMC of an event based on the age. If the adjusted upper bound is less than upper_cmc1, the function returns the error code of -1.
