code segment text segment <memory> ({Intel 8086} CS) The area of memory containing the {machine code} instructions of a {program}. The code segment of a program may be shared between multiple processes running that code so long as none of them tries to modify it. {Unix}, confusingly, calls this the "text segment" and the area for uninitialied data, the {bss segment}. Initialised data is located in the {data segment}. (1996-12-21)
