Y2K and forms

HELP! Can any one tell me how to force a user to enter a four digit year into a date variable? ODS 7.2x i4GL 6.x A picture clause of "##/##/###" only requires that the year portion is numeric. Format "mm/dd/yyyy" only works on display. And used with default = TODAY doesn't guarantee that the user will type four digits in the year. Resorting to i4GL code with an after field clause doesn't help either since the engine has already put the assumed century in the variable by the time you get there. We do not want to recode everything to use characters then convert. The first premise that we started with when dealing with Y2K was to remove all ambiguity whereever possible first. So we thought we would start with requiring that users key in all 4 digits, we thought this would be simply done with a picture clause in the .per. Any help will be much appreciated.
