Variable properties - values
In the Variable View, use the Values cell to enter a value label for any or all values of a variable. Click in the Values area of any variable. This brings up the ellipsis button. Click in this button to open the Value Labels dialog box:
The Value Labels dialog box specifies one or more values and the accompanying labels. Type the data value, type the label, and click on Add to add a new label. You can also use Change to change a highlighted existing label or Remove to delete a highlighted label.
Value labels are optional but are strongly recommended for categorical data or missing value data codes. Each value label can be up to 120 characters long. However, make the labels no longer than necessary. Note that SPSS's Custom tables and graph facilities produce more informative tables and charts by making use of value labels.
The equivalent syntax is the VALUE LABELS command.
