This file contains information and sample SAS programs to create a permanent                        
SAS dataset for users who want to use SAS in processing the CSPUF2019 transport data file                              
provided in this PUF release.                                                                       
                                                                                                    
Section A provides a sample SAS program to convert the SAS transport data file into a                             
regular SAS dataset using the SAS procedure: CIMPORT.  

Section B creates a format library.

Section C creates and applies labels to the datasets, which it saves as a permanent datasets 
(CSPUF2018) in the specified location (library PUFLIB)

A. This code converts the XPT files into temporary SAS datasets in library location given by LIBNAME.
The XPT files have been downloaded from the CMS website, and will be in a folder of your choosing.
