I do recall that the leading "." was a

HP BASICs of the 2114 era restricted filenames to letters and digits, so
neither the period nor the ampersand in ".D&D" would have been legal
without local modifications to the interpreter.
I had a quick squint at the contributed library catalog (e.g., "HP 2100
Program Catalog" at hpmuseum.net), and it seems as though all of the
contributed BASICs (including MSU BASIC) were modelled on the language of
the HP 20392 single-user product. None mention an ON...THEN statement.
With the ON...THEN statement and the different FILES syntax, I'm pretty
sure that this is either a non-HP BASIC, or it's a contributed library
BASIC that was locally modified.
