STSC built an APL compiler for mainframe APL users a few years ago (1986?). It works very nicely and as far as I know has no restrictions on what APL expressions can be compiled. I haven't heard of any APL compilers for PCs or MINIs yet. I suspect that any APL compiler is going to be VERY large and VERY slow (using current state-of-the-art compiler technology) and so impractical for small machines. Of course, now that we have the 16Mbyte 80486 machines, perhaps STSC will make the compiler available for it. Joseph T. Hatfield P.S. I DO work for STSC (as a consultant) however I do not represent them.

Tim Budd, now of Oregon State University (*not* University of Oregon) wrote a book: An APL Compiler Springer-Verlag, 1988 ISBN 0-387-96643-9 The compiler sources are still available (with standard disclaimers that always apply to research-grade software :-) via anonymous ftp from cs.orst.edu, in the pub/budd subdirectory, I believe. > IBM has, I am told, three different APL compiler projects.

Some of the IBM APL compiler projects that I am aware of (with journal/book references): Driscoll and Orth have a compiler, details in IBM J. of Res. & Dev. Nov. 86, "Compiling APL: The Yorktown APL Translator" Wai-Mee Ching, at IBM T.J. Watson, put together a compiler for the /370, with several related publications, including ones in: IBM J. of Res. & Dev. Nov. '86 APL Quote Quad 16(4), 1986 etc. Ching is currently working on generating parallel code from APL source, (as am I, for an MS project) as detailed in the book "Massively Parallel Computing" by Almasi/Gottlieb. -- Department of Computer Science | Rajeev Pandey Computer Science Building 100 | Internet: rpandey@cs.orst.edu Oregon State University | UUCP: hp-pcd!orstcs!rpandey Corvallis, OR 97331-3902 U.S.A. | Phone:(503) 737-3273 Fax: (503) 737-3014
