Funny; I thought EFL was also described in the same manual.
EFL is Feldman's Extended Fortran Language, which is somewhat
like RatFor except that it supports data structures and has
to interface with the second-pass code generator instead of
acting as just a preprocessor.

EFL is still distributed with UNIX System V, but some porters
are not porting it, for unknown reasons.  I doubt that it has
many users outside Bell Labs, and perhaps not many even there.
