Syntax

PSBII (BII)

Argument       Data Type      Access   Description
---------------------------------------------------------------------------
BII            Integer        Read     Back interior index
---------------------------------------------------------------------------

Description

PSBII sets the back interior index value, which points to the workstation interior bundle table.  Depending on the current edit mode, this function either inserts the new structure element directly after the element indicated by the pointer or replaces the element indicated by the pointer.  The pointer then points to the new set back interior index element.  If Digital PHIGS is in immediate mode, it performs this function immediately, but the function does not create a structure element. 

During structure traversal, Digital PHIGS sets the current back interior index entry in the PHIGS traversal state list to the specified value.  Digital PHIGS uses this value when displaying subsequent back-facing portions of area primitives. 

Digital PHIGS Version 3.1 does not support this function.
