Ken Knowlton sent me a paper from AFIPS 1964 on his BEFLIX language for creating animations (named from "Bell Flicks" as the work was done at Bell Labs). The language uses "MACRO FAP" as its implementation layer so to create a modern implementation of BEFLIX, I would need to know some things about "MACRO FAP". Google led me to this page: <http://www.softwarepreservation.org/projects/FORTRAN/source/ibsys/FORTRAN/9F04.fap/> Which seems to be the IBM 7090 assembly source code for the MACRO FAP program, from which I glean that "FAP" is an acronym for "FORTRAN ASSEMBLY PROGRAM". I don't know 7090 assembly, although I can guess at the opcodes. This leads me to the following questions: 1) How long has softwarepreservation.org been around? Its part of the CHM, but I haven't stumbled on this web site before. 2) Does anyone have any experience with MACRO FAP that can help me understand the semantics of MACRO FAP instructions? 3) Barring that, does anyone have any IBM 7090 assembly experience that can help me understand the semantics of the implementation of MACRO FAP so that I can understand the semantics of its command language? BEFLIX is actually quite interesting and could be fun in creating animated movies today. Its got a combination of simple 2D graphics primitives, turtle graphics and animation control in its command set. I'd like to write a BEFLIX interpreter for modern experimentation. Seeing as BEFLIX was created in 1964, its probably one of the oldest, if not the oldest, domain specific language for creating computer graphics animations. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
