**SAS TRANSPORT FILE NOTES:
--------------------------

Due to the manner in which SAS handles missing data definitions, the 
SAS transport file does not have in effect the missing data definitions 
found in the .SAS data definition file.
The SAS transport file was created using PROC CPORT and must be imported 
using PROC CIMPORT (not Proc Copy).  In Windows the commands would be
(for example):
    libname copy 'c:\copy';
    run;    filename trans 'c:\download\nesstues.xpt';
    proc cimport library=copy infile=trans;
    run;
(For other operating systems, the location and file naming conventions will 
differ.) The libname statement is for the location to place the .sd2 file.
The filename statement assigns the tag 'trans' to the location-filename of 
the transport file itself.
