Is there a neosBNF schema that describes the tokens of FORtRAN 66 or
Algol 60?

Not yet.

The definition of string literal of Algol 60 would be a good example
of something that cannot be defined with a regular expression and is
therefore impossible or at least complicated with an ordinary tokenizer.

Would you please be more specific about just what in an Algol 60 string
literal prevents a regexp from parsing it.  Not for any special reason,
just that I'm curious.  Maybe an example of such a string would be
interesting.  Thanks!
