Description

PSIASF sets ASFs for primitive attributes.  If the ASF is INDIVIDUAL, Digital PHIGS uses the value of the corresponding, individually specified attribute of the primitive on the workstation.  If the ASF is BUNDLED, Digital PHIGS uses the value of the corresponding component of the workstation-dependent bundle, pointed to by the bundle index. 

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 individual ASF element. 

During structure traversal, Digital PHIGS sets the ASF of the specified attribute identifier in the PHIGS traversal state list to the specified attribute source value. 

If Digital PHIGS is in immediate mode, it performs this function immediately, but the function does not create a structure element.
