|YEARCUTOFF= nnnn | nnnnn|
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.
