filename
Filenames, and the database name, may include directory information.
For example,
<"open '[zz99.elsewhere]hisdb'"
opens the database "hisdb" on the directory "[zz99.elsewhere]".
The name must be enclosed in quotes only if it
contains special characters.
VMS Rim assumes an extension of ".rim" for input files and
".lis" for output files.
Database files have the extensions ".rimdb1", ".rimdb2", and ".rimdb3".
