Christopher (et al),

I haven't seen it mentioned, but the reason the /36 allowed the dot (.) is to 
enable group files.  Since you couldn't have files in different libraries, 
you could group them by having a prefix, a dot, and a file name.  As was 
mentioned earlier, you could have files grouped by application (AR.), or you 
could group them by production or development files (PR., DV.).  Group files 
could be backed up or restored as a set, and it sure simplified (although 
nothing compared to the AS/400) establishing a test database.  Major packages 
of the time (DMAS, MAPICS, etc.) even incorporated renaming files to 
"nn.aaaa" prior to backup to prevent usage and renamed them back to ensure 
that backup was successful.

Cheers!
