The majority of the assembly code is concerned with device drivers and forcing things to hardware page boundaries and then it calls the actual program which is usually a PASCAL routine. So far, despite some rough edges, the system has been quite reasonable to use, and has a working multiprocess OS that supports real windows (unlike the fake windows on the PERQ - which do look nice, but presently can't have a processing running in each of them). It is unfortunate that your narrow linguistic understanding has blinded you to the realities of existing systems. It should be noted that the PRIME Computer systems early OS, which was largely take from and patterned after MULTICS was implemented in FORTRAN, and supported a virtual memory system with imbedded OS, and many of the other nice features of MULTICS with a very large address space for the time (early 70's). I think that given the efforts of groups at Brown Univ., Yale, Utah, Caltech, etc. You will see working systems which support C and LISP; as components in CAD/CAM, CAI, personal algebra machines, etc. Until such time as LISP systems are readily available for purchase for the 68000, as current PASCAL, FORTRAN, and C compilers are, it seems to be a perfectly reasonable "clever, conservative system" design which sells what is available rather than trying to sell what is not available as several other companies are presently doing! Chip ps To other Works readers: Sorry for the flame but I am very disappointed by many of the companies which are selling software and hardware which does not exist yet. ------- ----------------------------------------------------------------- gopher://quux.org/ conversion by John Goerzen of http://communication.ucsd.edu/A-News/ This Usenet Oldnews Archive article may be copied and distributed freely, provided: 1.
