Using proc cimport and proc cport

Warning: don't use Proc Cport to generate SAS transport file for submitting the data to FDA. See my article "Submit the Clinical Trial Datasets to FDA: Using the right .xpt file format"

Proc CPORT to creat SAS transport file

***This program will transfer all SAS data sets under c:\sourcedata directory 
***to a single .xpt file called test.xtp;

filename xptfile "c:\temp\test.xpt";
libname source "c:\sourcedata\";

***For converting a data set;
proc cport library=source file=xptfile memtype=data;
run;

***For converting a format catalog;
proc cport library=source file=xptfile memtype=catalog;
run;

Proc CIMPORT to extract SAS transport file

/*********************************************************************
/*  This program is used for extract the data from SAS transport file
/*  generated by using PROC CPORT
/*********************************************************************;

FILENAME xpt 'transport_file_name.xpt'; 
libname dest 'destination_directory_name'; 

PROC CIMPORT INFILE= xpt  LIBRARY=Dest; 
RUN;
