software

2006-08-28 Software needed for this course. (Also see the CD-ROM included with the textbook.)
DJGPP port of Gnu C/C++ to DOS/Windows environment
Run this to install it. Run the program goDJGPP.exe to start a command-line environment in which gcc will work.
portable SciTE editor
Simple text editor with syntax coloring. Good for many languages.
2006-10-25
Nasm assembler, version 0.98.39
Unzip this archive in the same directory as your DJGPP directory (if you have one). The nasm executables will install into djgpp's "bin" directory (and create one if it doesn't exist), and (re-)add the "goDJGPP.exe" utility that sets your path and starts a command-line environment.
Nasm documentation
In various formats: HTML pages, .pdf file, .ps file, plain ASCII, Windows .chm file.
