Memory Location Record
For fragments located in memory, the inMem field of a fragment location record contains a memory location record, which specifies the location of the fragment in memory. A memory location record is defined by the MemFragment data type.
struct MemFragment {
   Ptr                     address;       /*pointer to start of fragment*/
   long                    length;        /*length of fragment*/
   Boolean                 inPlace;       /*is data section in place?*/
};
typedef struct MemFragment MemFragment;
Field Description

address

length

inPlace
A Boolean value that specifies whether the container's data section is instantiated in place (true) or elsewhere (false).

The fields of a memory location record are aligned in memory in accordance with 680x0 alignment conventions.
