t the numeric or short string variables for which you want to create value labels
or define or change other variable properties, such as missing values or descriptive
variable labels.
Note: Long string variables (string variables with a defined width of more than eight
characters) are not displayed in the variable list. Long string variables cannot have
defin
ed value labels or missing values categories.

particularly useful for data files with a large number of cases for which a scan of the
complete data file might take a significant amount of time.
E Specify an upper limit for the number of unique values to display. This is primarily
usefu
l to prevent listing hundreds, thousands, or even millions of values for scale
(continuous interval, ratio) variables.
