Year 2000 sliding rule

Type the two digit cutoff value in the Year 200 sliding rule field.

This cutoff value is used by ISPF to determine whether a 2 character year date specified to ISPF should be considered a 19xx or 20xx date. Values less than or equal to this date will be considered 20xx, values greater will be considered 19xx. The value can be an absolute number or a number preceded by a minus sign to indicate the cutoff should be the specified number of years prior to the current year.

For example, specifying 72 indicates that any 2 character year less than or equal to 72 should be considered 20xx, anything greater should be 19xx. Specifying -40 (assuming the current year is 1999) will yield a cutoff value of 59. Valid values range from -99 to 99.

The default is 65.
