LIST.
• WKDAY reads and writes the day of the week; MONTH reads and writes the month of the
year.
• Values for WKDAY are entered as strings but stored as numbers. They can be used in
arithmetic operations but not in string functions.
• Values for MONTH can be entered either as strings or as numbers, but are stored as
numbers. They can be used in arithmetic operations but not in string functions.
• To display the values as numbers, assign an F format to the variable, as was done for VAR2
and VAR5 in the above example.
