Variable properties - label

In the Variable View, use the Label cell to enter a variable label for each variable. Note that variable labels are optional. A variable label has a maximum length of 256 characters and can consist of spaces or any character.

While the limit is 256 characters, make labels no longer than necessary as procedures will not necessarily display all 256 characters or might wrap the labels in an unsightly way.

The equivalent syntax is the VARIABLE LABELS command.
