Thanks!  I asked on cctalk and that didn't turn up.

Indeed.

Well, it *is* written in 7090 MACRO FAP, but I don't have a source
listing for BEFLIX, only a paper describing the commands in its
language.  I realize now that the "commands" are not really a native
language at all, but instead are FAP macros that expand into something
that implements BEFLIX operations.  At some point Ken Knowlton, the
creator of BEFLIX, turned it into a FORTRAN subroutine library, at
which point I find the language gets less interesting.

However, the language is interesting and has historical significance
in computer graphics for being one of (if not *the*) first domain
specific languages for generating graphics and animations.
