Chapter —Program Instructions
Purpose Function returning a new date after a number of days have been added to,
or subtracted from, the current date or optionally a specified date.

number of days should be added to or subtracted from.
is the number of days to be added to (or subtracted from) the
current date or optionally the date specified by .
is one or two optional flags "F" or "M":
"F" specifies that the date will be returned according to the
format specified by FORMAT DATE$.
"M" specifies the value given in will mean months
instead of days.
Remarks The original date () should be entered according to the syntax for
the DATE$ variable, that is in the order YYMMDD, where:
YY = Year Last two digits (for example 2003 = 03)
MM = Month Two digits (01-12)
DD = Day Two digits (01-28|29|30|31)
Example: December 1, 2003 is entered as "031201".
The built-in calendar corrects illegal values for the years 1980-2048, for
example the illegal date 031232 will be corrected to 040101. When for
example, adding one month to the date 2004-01-31, the result will be
rounded off to 2004-02-29 (2004 is a leap year).
The number of days to be added or subtracted should be specified as a
positive or negative numeric expression respectively.
If no "F" flag is included in the DATEADD$ function, the result will be
returned according to the DATE$ format, see above.
If the DATEADD$ function includes an "F" flag, the result will be returned
in the format specified by FORMAT DATE$.
"F" and "M" flags can be combined in the same instruction without any
separating character, that is, "FM" or "MF". No other characters are accepted.
