specifies the first year of the 100-year
span.
Range: |
1582-19900 |
Default: |
1920 |
The YEARCUTOFF= value is the default that
is used by various date and datetime informats and functions.
If the default value of nnnn (1920) is
in effect, the 100-year span begins with 1920 and ends with 2019. Therefore,
any informat or function that uses a two-digit year value that ranges from
20 to 99 assumes a prefix of 19. For example, the value 92 refers to the year
1992.
The value that you specify in YEARCUTOFF= can result
in a range of years that span two centuries. For example, if you specify YEARCUTOFF=1950,
any two-digit value between 50 and 99 inclusive refers to the first half of
the 100-year span, which is in the 1900s. Any two-digit value between 00 and
49, inclusive, refers to the second half of the 100-year span, which is in
the 2000s. The following figure illustrates the relationship between the 100-year
span and the two centuries if YEARCUTOFF=1950.

Note: YEARCUTOFF= has no effect on existing SAS dates
or dates that are read from input data that include a four-digit year, except
years with leading zeros. For example, 0076 with yearcutoff=1990 indicates
2076. ![[cautionend]](../../../../common/63294/HTML/default/images/cautend.gif)
