The DATE-TO-YYYYMMDD Function

General Format

    FUNCTION DATE-TO-YYYYMMDD ( argument-1 [argument-2] )

Arguments

  1. Argument-1 must be a positive integer less than 1,000,000.
  2. Argument-2 must be an integer.
  3. If argument-2 is omitted, the function is evaluated as though 50 were specified.
  4. The sum of the year at the time of execution and the value of argument-2 must be less than 10,000 and greater than 1699.

Returned Values

  1. The equivalent arithmetic expression is:

    (FUNCTION YEAR-TO-YYYY (YY, argument-2) * 10000 + nnnn) where:

      YY = FUNCTION INTEGER (argument-1/10000)    nnnn = FUNCTION MOD (argument-1, 10000)

    and where argument-1 of the INTEGER and MOD functions and argument-2 of the YEAR-TO-YYYY function are the same as argument-1 and argument-2 of the DATE-TO-YYYYMMDD function itself.

Notes

  1. In the year 2002 the returned value for FUNCTION DATE-TO-YYYYMMDD (851003, 10) is 19851003. In the year 1994 the returned value for FUNCTION DATE-TO-YYYYMMDD (981002, (-10)) is 18981002.
  2. This function supports a sliding window algorithm. See the notes for the YEAR-TO-YYYY function for a discussion of how to specify a fixed window.
