This example is based on sas-codebook\ExampleFiles\test_generic.sas.
It utilizes the dataset sas-codebook\ExampleFiles\cars.sas7bdat.

In the SAS program, edit the &zippath macro variable to point to the location in which you extracted the sas-codebook zip file. This location is used in both the SASAUTOS and LIBNAME definitions.

*---------- tell SAS where you put everything ----------;

%let zippath = H:\GitHub\sas-codebook;
options sasautos=("&zippath\Macros" sasautos);
libname examples "&zippath\ExampleFiles";

*---------- run the macro on the local copy of the CARS dataset ----------;

%codebook_generic(data=examples.cars)
