Two of these pertain to the sensing and use of the 8087 co-processor, and the other concerns the use of the "malloc'° and "getmem" functions under MS-DOS 1 in the s and P models of the compiler. In addition some code was oMtted from the file " main.c". 1. Floating Point Bugs (a) Sensing cjf the 8087 The technique employed in the run-time library to sense the presence of the 8087 co-processor does not work in V2.14 because the 8087 is not initialized prior to the test. Correcting this problem is rather easy. You need only add a line of code to the file °'c.asm" provided with the compiler and reassemble this to replace the current "c.obj". file In the file "c.asm" you will find a line: CALL JLAIN just prior to this line, insert the fcülowing line DB ODBh,OE3h ; FNINIT instruction Then reassemble "c.asm" for each of the memory models as follows: -- Copy "c.asm" to the appropriate model subdirectory (i.e., \lc\s, \lc\d, \lc\p, or \lc\l) so that is in the same directory as "dos.mac" for it the appropriate memory mcdel. -- Use the command 1 @ LATTICE,1NC.

  • The Atari™ Compendium ©1992 Software Development Systems Written by Scott Sanders Not for Public Distribution
    The Atari™ Compendium ©1992 Software Development Systems Written by Scott Sanders Not for Public Distribution Introduction The following pages are a work in progress. The Atari™ Compendium (working title) is designed to be a comprehensive reference manual for Atari software and hardware designers of all levels of expertise. At the very least, it will (hopefully) be the first book available that documents all operating system functions, including any modifications or bugs that were associated with them, from TOS 1.00 to whatever the final release version of Falcon TOS ends up being. GEMDOS, BIOS, XBIOS (including sound and DSP calls), VDI, GDOS, LINE-A, FSM, AES, MetaDOS, AHDI and MiNT will be documented. Hardware information to the extent that information is useful to a software programmer will also be covered. This volume will not include hardware specifications used in the creation of hardware add-ons, a programming introduction designed for beginners, or an application style guide. All of the aforementioned exclusions will be created separately as demand for them arise. In addition, I also plan to market a comprehensive spiral- bound mini-reference book to complement this volume. By providing early copies of the text of this volume I hope to accomplish several goals: 1. Present a complete, error-free, professionally written and typeset document of reference. 2. Encourage compatible and endorsed programming practices. 3. Clear up any misunderstandings or erroneous information I may have regarding the information contained within. 4. Avoid any legal problems stemming from non-disclosure or copyright questions. A comprehensive Bibliograpy will be a part of this volume.

  • Application of Microcomputers 1N Bridge Design
    Transportation Research Record 1072 15 Application of Microcomputers 1n Bridge Design RONALD A. LOVE, FURMAN W. BARTON, and WALLACE T. McKEEL, Jr. ABSTRACT The use of microcomputers in bridge design activities in state transportation departments was evaluated through contacts with 32 state agencies. Although pres­ ent use of microcomputers was found to be 1 imi tea, subsequent research showed that the current generation of 16-bit machines offers significant advantages in complementing existing computing facilities in a manner that fully uses the power of both mainframe and microcomputer. The ability of microcomputers to run large bridge design applications in a stand-alone mode was demonstrated by successfully downloading and converting four mainframe programs. Running design and analysis programs in a stand-alone mode frees the mainframe CPU and increases access to software that can be run repetitively without consideration of mainframe costs. When access to larger applications on the mainframe is required, the microcomputer used as an intelligent terminal can process input data locally and send them to the mainframe for processing. Output data, in return, can be downloaded to the microcomputer and reviewed off-line or input into microcomputer applications such as spreadsheets or graphics packages for further processing. Computer applications in engineering design have had preferred alternative for using much of the bridge a dramatic effect on the analysis and design process design software available.

  • Your Format - QL
    Your Format - QL QL columns from New Computer Express magazine in the 1980s. Written by Paul Connell, Eric Simmonds, Robert Myers and John Torofex. At various times, these columns were called either “QL Corner” or just “Your Format >QL” These columns are reproduced as one per page in date order. If anyone has copies of further columns from this series, I’d be very pleased to scan them and add to this document. YOUR FORMAT – QL 12/11/1988 The emulation game With the Atari ST now running a creditable QL Emulator and the QL running a CP/M Emulator, news is of a PC emulator for the QL in the final stages of polishing. It is the lack of volume of some forms of business and bespoke software which is the biggest frustration to QL users, and this emulator may be the best solution. The writers have employed some ingenious tricks to speed up the resulting product on the QL. It appears DOS spends a lot of its time doing error checking and housekeeping which would be taken care of by the native QDOS built in to the QL anyway, so a large part of the normal DOS kernel is redundant. The QL was offered with the Psion suite as an all-in package and as a result there was never any market in the formative years for alternative spreadsheet/database systems. The major software item to influence QL development has been the Superbasic compilers. Thts emulator, when released, will equal their impact. Discover DiscOVER DiscOVER is a utility that is a lifesaver to those who need to transfer data from QL to PC and/or back.
