The +procedure RCURSOR is the main entry point for cursor mode. RCURSOR is called +by the CL to service a query for a cursor type parameter when query mode is +in effect. The workstation transformation is used to zoom and pan on a frame +buffer and consists of a viewport transformation in GKI coordinates with +clipping at the viewport boundary. |
