When in a cluster directory, you can look at the data file:
> ls or ls -l
Do not forget that the files are compressed, so they have the
suffix ".Z". You can uncompress them with the uncompress system
command or with testfZ which uncompresses the file and writes its name
and path in the file fich_compr located in bda/gestion/.
At the end of the work session the files are automatically recompressed if
the command recompress has been added in the .logout file.
