SEGI\1EN'r INDEX values 1 throuqh 327fi7, which are used in other record types to refer to specific LSEG's, are defined implicitly by the sequence in which SEGDEF Records appear in the object file .

(SEGMENT INDEX 0 is reserved to indicate the ·unnamed absolute

seqment", which is not really a seqment: it is a possibly empty set of possibly disjoint regions of memory; it is normally created by LOCATE-86, although translators may create portions of it as well, if they wish.)
