Table label retrieval macro

This macro, `dslabel`, is designed as a utility function. It takes a SAS^© table name as a parameter (`ds`) and uses the `%attrc` sub-macro (assumed to be available in the SAS^© environment) to extract and return the label associated with that table. Its primary purpose is metadata extraction, and it does not perform any data processing.

Data Analysis

Type : EXTERNE

The macro expects a SAS table name (`ds`) as input. The origin of this table (internal, SASHELP, external) is not managed or specified by the macro itself, but by the calling environment. The macro simply reads the metadata of this table.

1 Code Block

Instruction %PUT

Explanation :
This instruction writes a message to the SAS log, indicating that the `dslabel` macro has been called and specifying its version. This is a common practice for debugging or tracking macro execution.

Définition de la macro dslabel

Explanation :
This is the definition of the `dslabel` macro. It takes a positional argument `ds`, which represents the name of a SAS table. Inside the macro, it calls the `%attrc` sub-macro, passing the table name (`&ds`) and the `label` attribute. The `%attrc` macro is responsible for retrieving the value of the 'label' attribute for the specified table and returning it. The `dslabel` macro is therefore a simple wrapper facilitating access to this functionality.
