CALL PDST (STRID)
DELETE STRUCTURE deletes the structure STRID from the centralized structure store (CSS).
When STRID designates a closed structure:
The structure STRID in the CSS is destroyed; its identifier, its elements and all the references to STRID in the other structures are destroyed. If the structure is posted on a workstation, it is unposted.
If the open structure contains a reference to STRID , the element is then destroyed and all the following elements are renumbered. If the element destroyed was indicated by element pointer, element pointer then points to the previous element.
When STRID designates the open structure:
In this case, the open structure is replaced by a non-referenced empty structure. The effect is similar to calling the functions: CLOSE STRUCTURE, DELETE STRUCTURE and OPEN STRUCTURE.
The effect of this function can differ from the standard if used in combination with GPHIGS extended view extensions. The structure is not unposted with the standard UNPOST STRUCTURE function, it is unposted by calling UNPOST STRUCTURE FROM ALL VIEWS.
