Variable Label

When running the PRINT procedure, you can print the variable label as opposed to the variable name by adding the LABEL option.

Example

Copy and run the CARRIER data set from the yellow box below. 

Data Carrier; Input Order :$12. Date :Date9. Length Width Height Weight; Label Length = "Length (inch)"; Format Date Date9.; Datalines; AC-DC-0142 01MAR2015 12 10 4 10 AC-DC-0143 01MAR2015 18 15 6 15 AC-DC-0144 01MAR2015 15 14 14 16 AC-DC-0146 02MAR2015 16 13 20 18 AC-DC-0148 02MAR2015 9 20 16 5 AC-DC-0149 02MAR2015 15 19 6 6 AC-DC-0151 03MAR2015 22 34 9 20 AC-DC-0155 03MAR2015 40 24 30 30 AC-DC-0156 03MAR2015 21 19 3 10 AC-DC-0157 03MAR2015 20 20 14 15 ; Run;

The LENGTH variable is currently assigned the label of "Length (inch)".

At the top of the data set, select "Variable Label" from the View menu:

The data set will show the label instead of the variable name.

Although the LENGTH variable has a label assigned to it, the PRINT procedure prints the variable name by default.

Example

Proc Print Data=Carrier;
Var Order Length Width Height;
Run;

The label of the variable LENGTH isn't displayed in the output.

To display the label instead, simply add the LABEL option to the PRINT procedure.

Example

Proc Print Data=Carrier Label;
Var Order Length Width Height;
Run;

The LABEL option is added to the PRINT option.

The output will display the label as opposed to the variable name.

Adding a label in the PRINT procedure

What if the variable isn't assigned a label to begin with?

You can add the label in the PRINT procedure as well.

Example

The WIDTH variable isn't assigned a label:

A label can be added to the WIDTH variable with a LABEL statement.

Example

Proc Print Data=Carrier Label;
Var Order Length Width Height;
Label Width = "Width (inch)";
Run;

The LABEL statement is added to the PRINT procedure.

The output will display the variable Label instead.

Important Note

When adding the LABEL statement to the PRINT procedure, don't forget to add the LABEL option as well.

Otherwise, the label wouldn't be displayed in the output despite the present of the LABEL statement.

• ORDER

• HEIGHT: Height (inch)
