Thank you for the comments. It turned out that I can use SAS 8.1 for VAX/VMS and set these lines to create XPORT file
LIBNAME a v8 '';
libname b XPORT '';
PROC COPY IN=a OUT=b;
and the first lines of the file looked very different indeed. Any comments ?
Does updated version of SAS produce different transport file ?
I'm sure read.xport does not read this file.
