SAS reads data in one
of the following forms:
yy or yyyy
is an integer that
represents the two-digit or four-digit year.
q
is an integer (1, 2,
3, or 4) that represents the quarter of the year. You can also represent
the quarter as 01, 02, 03, or 04.
The letter Q must separate
the year value and the quarter value. The year value, the letter Q,
and the quarter value cannot be separated by blanks. A value that
is read with YYQw. produces
a SAS date value that corresponds to the first day of the specified
quarter.
Note: SAS
interprets a two-digit year as belonging to the 100-year span that
is defined by the YEARCUTOFF= system option.
