assembly language. A module is a unit of assembly language comprising a main
program, subroutine, or data variable declarations. C programmers write C
language files and use the C compiler to create assembly code modules from
them. Assembly language programmers write assembly code modules directly.
Each code module is assembled separately by the assembler.
The linker links several modules together to form an executable program
(memory image file). The linker reads the target hardware information from the
architecture description file to determine appropriate addresses for code and
data. In the assembly modules you may specify each code/data fragment as
completely relocatable, relocatable within a defined memory segment, or non-
