The date your are trying to assign is a string, dates in SAS a numerical.

If you wish to express a data constant, you need to use the date format and using a data literal:

'01Jan205'd

The value of a Date literal must be in the form of 'ddMONyy'd or 'ddMONyyyy'd for SAS to recognize it as a date. If you have assigned a format of mmddyy10. to the variable then that is the default appearance the value will have in your data set.
