On that front, I now have a working parser. Or more precisely, there exists
at least one program that does not cause bison to spit out its oh-so-helpful
"syntax error" message.

DATA is a bugger though, isn't it? Free-form so needs special treatment
(fortunately within the scope of flex start conditions) and a READ into a
numeric variable is really a string read with an EVAL. Eww.
