the KNOWNHOST list.
Unfortunately, it appears that the file formatting depends on the system
where is was originally written. The hypothesis is that sas7bdat files
were originally no more than a memory dump of a C structure, or similar.
Because C structures may be laid out differently by different compilers
(i.e., on different platforms), this may have led to the difficulty
