- ******************************************************************
-
- The source code files on this disk are from Programmer's Journal,
- Volume 9.3, May/June 1991. These files are identical to those
- published in the magazine, except where noted; OBJ and EXE files
- have been added.
-
- The copyrights are held by the programs'authors, as indicated in the
- files. All other rights are reserved by Oakley Publishing Company,
- 1991. No one may commercially distribute these files. Every effort
- has been made to assure that the program files are correct and
- complete. No guarantee, express or implied, is offered as to the
- correctness of the files, nor to the fitness of the programs for
- any purpose whatsoever.
-
-
- Files from Volume 9.3 are as follows:
-
- Code from "Pixel Panning" by Peder Jungck
-
- Ever wondered how arcade games simulate motion and generate
- such smooth action images? Wonder no more. Peder explains how similar
- feats are possible on the EGA and VGA using fast panning to window
- onto a "larger than life" screen.
-
- PIXELPAN.ASM Assembly language routines for pixel panning
- designed for C-style calling conventions
- PANTEST.C Testing code that displays color blocks and then pans
- the display
- PANTEST.EXE An executable version
- PANTEST2.EXE An executable version with macro SLOW_EGA set to 1
-

-
- Code from "Object-Oriented SCSI Programming" by Brett Glass
-
- Although other PC hardware interfaces have long been standardized,
- SCSI programming has remained a free-for-all. Brett looks at the latest
- proposed Common Access Method (CAM) standard for SCSI and writes some
- portable code to interface with SCSI devices using Turbo Pascal objects.
-
- CAM.PAS A Turbo Pascal unit that implements an object-oriented
- interface to BallardSynergy's CAM SCSI drivers
- CAMTEST.PAS A simple test program to see what SCSI devices are attached

-
- Code from "Numeric Exception Handling" by Mark J. Barrenechea
-
- Floating-point errors have puzzled programmers for too long.
- Mark demystifies the IEEE 754 and 854 floating-point standards and
- explains how the Intel 80287/80387 and i860 chips fit into the puzzle.
- Learn some slick techniques for handling numeric exceptions in C++
- with ease and elegance.
-
- EXCEPT.CPP A simple program illustrating numeric exception
- handling in C++
- EXCEPT.EXE An executable version using Zortech C++
-
-

-
- Code from "Virtual Realities" by Stephen M. Kuhn
-
- When your text-based application can no longer deal with
- the memory-hungry real world, it's time to go virtual. Stephen shows
- you how to select and develop an application-supported virtual memory
- system that can take advantage of EMS paging and disk storage.
-
- VMHEADER.H Some useful structures for a VM application
- TOKEN.C Some sample code illustrating the use of VM calls
-
-
- ********************************
-
- Code from "Basic Libraries" by Murray L. Lesser
-
- Our BASIC ace shows how to manage personal link libraries. Along the
- way, he provides two utilities that streamline library management and
- explains how to shrink applications by linking stub modules.
-
- COMMAND.ASM Subroutine to insert "rest of command line" in PSP
- for Microsoft BASIC Compiler v7.0
- COMMAND.OBJ An object code module for your library
- DOLIB.BAS A BASIC program to update private libraries
- DOLIB.EXE An executable version
- FINDFILE.BAS Two BASIC functions to find files in a directory
- and strip out the filename and extension from the
- full subdirectory and filename string
- FINDFILE.OBJ An object code module for your library
- PBBI.BAS A BASIC program to update the declaration header file
- for BASIC library maintenance
- PBBI.EXE An executable version
-
-
- ********************************
-
- Code from "Hashing Functions" by John Otken
-
- John examines string hashing functions for fast table lookup
- and explains why a hash table, unlike your car's gas tank, should
- never be full. He also creates equivalent functions in assembly language
- for Windows 3 routines that manage handle-based dynamic storage and
- atoms (hashed strings).
-
- ASM.INC A revised include file with macros
- ATOM.ASM Atom functions
- DOS_ERRS.ASM MS-DOS interface that sets error string
- FATAL.ASM Fatal error routine
- GLOBAL.ASM Global storage routines
- MALLOC.ASM Memory allocation and free routines
- MISC.ASM Miscellaneous support routines
- PERROR.ASM Routine to print error messages
- PUTCHAR.ASM Output a single character routine
- PUTS.ASM Output a string routine
- STARTUP2.ASM Start up code for assembly language
- STREAM.ASM Stream I/O routines
- STRERROR.ASM Error message interface routines
- STRNCPY.ASM String copy routine
- TESTATOM.ASM Program to test the atom routines
- TESTATOM.EXE An executable version of the TESTATOM program
- TESTATOM.MAK A make file to create the TESTATOM program
