RVF restores the image, graphics, frame directory, navigation, image enhancement and the graphics table that were present on each of the frames when they were saved with command SVF. Full image and graphics functionality is retained so you can use commands like EG, ERASE, EU, GU, K and W. If you're running a session with independent graphics, you can also use commands like SF, SG, J and Y to display or loop the restored image and graphics frames independently.
Virtual frames can only be restored to frames the same size as the original. Use command LVF with FORM=ALL to list the size of each of the virtual frames so you can restore them to frames of the correct size with RVF.
The frames specified in RVF acquire the panel configuration that the virtual frames had when they were saved with the SVF command. For example, if a virtual frame with four panels is restored to a single-panel frame, the frame is reconfigured to have four panels.
Frames saved with SVF on little endian workstations (e.g., PC systems) can only be restored with RVF on the same workstation or other little endian workstations. Likewise, frames saved with SVF on big endian workstations can only be restored with RVF on the same workstation or other big endian workstations.
Use the SVF command to save virtual frame files. Use LVF to list virtual frame files.
