Usage Note 22656: How to determine the creation method of a SAS transport file
A transport file can be created with any of the following:
- PROC COPY or a DATA step with the XPORT engine
- PROC XCOPY or PROC COPY with the SASV5XPT engine
- PROC CPORT
If the creation method of a transport file is unknown, you can determine how the file was created using the following method.
Run the following DATA step:
filename tranfile 'physical_storage_location';
data _null_;
infile tranfile obs=5;
input theline $ascii80. ;
put theline;
run;
Note:
The $ASCII. informat was not available in Release 6.04. The following DOS command will be helpful.
c:> type c:\tranfile.dat | more
When you check your SAS Log (or your screen if you are DOS command above), you will see one of two possible displays. If the first line of the display contains LIBRARY HEADER RECORD, the transport file was made by either PROC COPY with the XPORT engine (SAS Release 6.06 and higher), PROC COPY with the SASV5XPT engine (SAS Release 6.04), or PROC XCOPY.

NOTE: 5 records were read from the infile TRANFILE.
If you see a **COMPRESSED** line, as shown below, the transport file was created by the CPORT procedure.

Operating System and Release Information
*
For software releases that are not yet generally available, the Fixed
Release is the software release in which the problem is planned to be
fixed.
This note illustrates how to determine the creation method of a SAS transport file if the method is unknown.
