The DATASOURCE Procedure

LABEL Statement

LABEL variable = "label" … ;

The LABEL statement assigns SAS variable labels to variables in the output data sets. You can give labels for any number of variables in a single LABEL statement. The default labels for variables depend on the file type. Extra-long labels ( > 256 bytes ) reside in the OUTCONT data set as the DESCRIPT variable.

Any later label specification for a variable, using either the LABEL statement or the LABEL= option in the ATTRIBUTE statement, always overrides the previous one.
