WEEKDAY$
Purpose Returning the name of the weekday from a specified date.
Syntax WEEKDAY$()
is the date for which the name of the weekday, according to a
list of weekday names created by means of NAME WEEKDAY$
statement , will be returned.
Remarks This function returns the name of the weekday according to a list of weekday
names specified by means of NAME WEEKDAY$ statement or—if
the name is missing—the full English name in lowercase characters, for
example “friday".
The date should be entered according to the syntax for the DATE$ variable,
that is in the following order:
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.
Example This example shows how to make the printer return the name of the weekday
as a three-letter English abbreviation in connection with a formatted
date:
10 FORMAT DATE$ ", MM/DD/YY"
20 DATE$="031201"
