The GROUP INDEX field has a format qiven earlier, and provides

anumber between 0 and 32767 inclusive. A non-zero GROUP INDEX "associates· a qroup with the public sym~ol, and is used as described on paqe 16, case (F2c). A zero GROUP INDEX indicates that there is no associated qroup.

The SEGMENT INDEX field has a format qiven earlier, and provides a number between 0 and 327~7 inclusive.

Anon-zero SEGMEN~ INDEX selects an LSEG, in which case the location of each public symbol defined in the record is taken as a non-neqative displacement (qiven by a PUBLIC OFFSET field) from the first byte of the selected LSEG, and the FRAME NU~BER field must be absent.

A SEGMENT INDEX of 0 (leaal only if GROUP INDEX is also ~) means that the location of each public symbol defined in the record is taken ~s a displacement from the base of the FRAM~ rlefined by the value in the FRAME NU~8ER field.
