You can do it in syntax with the MISSING VALUES command, but an easier way is to use Data/Define Variable Properties, where you can see a list of all the actual values in the data (along with counts), and you can just check the missing box next to the appropriate values.

Define Variable Properties does not support the range option for missing values.

In syntax it would be something like

missing values bdate('01/11/1966').

where the date/time literal is quoted and in the format of the date/time variable in question.

Define Variable Properties was introduced in SPSS 11.5. I think we made the Missing Values command accept date/time literals in that same release.

Dear list: I have some invalid times (HH:MM) that I want to declare as missing but the variable view doesnot allow me to declare anything as missing. Does anyone know how to declare a time as missing. TIA.
