SPSS Missing Values
The MISSING VALUES command sets user missing values for a variable.
Contents
Usage

missing values ham spam eggs ('NULL').The forward slashes (/) are optional.
Specifying no values between the parentheses (()) is equivalent to deleting the user missing values setting for a variable.
Up to three user missing values may be specified. If a numeric range is specified, up to one other user missing value may be specified.
The keywords HI/HIGHEST and LO/LOWEST dynamically capture the highest and lowest value. They are valid only in a numeric range.
