HiSoft Devpac 3 (called simply HiSoft Devpac from now on) is a complete package for the production of fast, efficient assembly language programs on your Amiga computer.

There is an editor for the creation and editing of your assembler source code, a linker for building your programs together with other object files, a debugger for helping you to stamp out those nasty bugs (problems) and, of course, an assembler to turn your source code into speedy, compact machine code.
