Mapping object module END section-length elements

OBJ END records can supply the length of a section whose length was not known at the time the ESD SD item was produced. In the GOFF format, this information is provided on a new type of record ("LEN"), which must be emitted ahead of the END record. It is shown in Table 1. Note that the length must be that of an element, not of a program object section, which has no text or length associated with it. Note also that while OBJ END records can supply only a single deferred length (for a single SD item), GOFF records can accommodate multiple deferred lengths.

Table 1. Mapping OBJ END section–length items to GOFF format
OBJ Element	GOFF Element
END with section length	Emit a deferred-length record with Length 12, and data as follows: 4-byte EDID for the element whose length is being provided. 4 byte reserved field, set to zero. 4-byte length for the specified element.
