808~ Object Module- Formats

Version 4.1

The format and the interpretation of the above REGISTER BASE field is identical to the LOCAL SY~BOL BASE described in the LOCSYM record.

The REGISTER OFFSET field (present only if REGID <= 1)

specifies an offset relative to the Seqment (if SEGMENT INDEX ) 0) or to the FRAME (if SEGCt1EN'r INDEX = 0) •

(Note) Once the seqments and/or groups are absolutely located (by a loader or LOCATE-8~),the base of the object pointed to by the REGISTER BASE

field is the appropriate value for the initialization of the corresPQnding base reqister. The offset value for the initialization of either the IP reqister

(REGID = 0) or the SP reqister (REGID = 1) is determined as follows:

If GROUP INDE·X = 0, the offset value is given by the value specified in the REGISTER OFFSET field.

If GROUP INDEX > 0, the offset value is the offset relative to the base of the specified qroup of the location specified by the pair (SEGMENT INDEX,

REGISTER OFFSET). (End of Note)
