The DATE-TO-YYYYMMDD function converts argument-1 from the form YYnnnn to the form YYYYnnnn. Argument-2, when added to the year at the time of execution, defines the ending year of a 100-year interval, or sliding window, into which the year of argument-1 falls.
The type of the function is integer.
Format
>>-FUNCTION DATE-TO-YYYYMMDD--(argument-1-+------------+-)-----><
'-argument-2-'
The equivalent arithmetic expression is:
(FUNCTION YEAR-TO-YYYY (YY, argument-2) * 10000 + nnnn)
where
YY = (argument-1/10000) truncated to an integer value nnnn = argument-1 modulus 10000
This function supports a sliding window algorithm. See YEAR-TO-YYYY for a discussion of how to specify a fixed window.
