code segment การใช้

This includes all sorts of active memory regions like code segment containing ( mostly ) program instructions ( and occasionally constants ), data segment ( both initialized and uninitialized ),
Array access analysis aims to obtain the knowledge of which portions or even which elements of the array are accessed by a given code segment ( basic block, procedure level ).
In the " small " memory model DS = SS, so both data and stack reside in the same segment; CS points to a different code segment of up to 64 KB.
An executable file might consist only of resources ( including code segments ) with an empty data fork, while a data file might have only a data fork with no resource fork.
This defeated one of the features of the 80286, which makes sure data segments are never executable and code segments are never writable ( which means that self-modifying code is never allowed ).
