Description

pset_int_rep_plus allows you to modify the entries in the extended interior bundle table in the workstation state list by defining a new index. The extended interior bundle table in the workstation state list has predefined entries taken from the workstation description table. A number of these entries are predefined for every workstation of category OUTPUT and OUTIN. You can redefine any table entry using this function, including predefined entries.

When Digital PHIGS displays area-defining primitives during structure traversal, the current interior index in the PHIGS traversal state list refers to an entry in the extended interior bundle table. If the current interior index is not present in the extended interior bundle table, Digital PHIGS uses interior index 1. The setting of the corresponding aspect source flags determines which of the aspects in an entry Digital PHIGS uses.

During structure traversal, if the current interior index does not exist in the extended table, Digital PHIGS uses interior index 1.
