Greg,
If you use SET CENTURY TO 19 ROLLOVER 20 my mother's birthday 01/10/19 would convert to 01/10/2019 instead of the correct 01/10/1919.

I think you woud want to use either
SET CENTURY TO 19 ROLLOVER 8 && good for two months then change the 8 to 9
or
rollyear = VAL(SUBSTR(STR(YEAR(DATE()) + 1),3,2))
SET CENTURY TO 19 ROLLOVER rollyear && gives you 99 years ago
