Can anyone shed any light on this? UIS (also known as VWS - VWS is the official product name, i.e., what you have to order from SDC, and UIS is the facility name, i.e., the prefix used on calls, like UIS$CREATE_TERMINAL) is a windowing and graphics system that is specific to VAXStations running under VMS. While this is not an exact analogy, you can think of using UIS as making direct calls to RMS services. GKS (Graphics Kernel System) is an industry-standard graphics interface. There are implementations of GKS on a wide variety of graphics devices. On VAXStations, GKS uses UIS to actually write to the screen. If using UIS is like calling RMS directly, then using GKS is like writing FORTRAN PRINT and FORMAT statements. -- Jerry -------
