A codebook is a report which provides information about the variables in a dataset. The information presented varies from one codebook package to another, but codebooks typically contain information such as: the variable type, label, number of cases, each level of categorical variables, means, and other statistics for continuous variables.

There are already many very good SAS^®-based codebook programs out in the world, so why create yet another codebook program? The short answer is, "pictures!"

The repository sas-codebook actually contains SAS code for 3 different types of reports:

1. A codebook for generic datasets.
2. A codebook for vertical datasets.
3. A codebook that produces paneled graphics.

Check out the other wiki pages (links at right) for more details about each of these different types of reports.
