Duncan I looked at support.sas.com/techsup/technote/ts140.pdf and it is a bit difficult to decipher. I then replaced the string "^@" in the file contents with "!". There is some concordance with he sample text shown in support.sas.com/techsup/technote/ts140.pdf but I don't know exactly how much concordance is expected. The time stamp in the file is today so I assume that the file was created today.
You asked "why [I] think this is a file that follows the format" -- I did not make that assumption; I merely attempted to read an XPT file with read.xport and it failed. Could there be an issue with the version of SAS (which appears to be 6.06) -- they are now up to version 9 (for Windows - I don't know the version # for UNIX).
