The auto-download system includes automatic version checking to make sure that the program and/or images residing on the workstation are the same version as the copies on the host. If the host version has a different last date modified, the host version will be downloaded again to the workstation. This guarantees all the images and programs at the workstation will be the most current at all times.

Using the '+U' system parameter you can control the Auto-download feature:

• '+U' = 0 -- No auto-download
• '+U' = 1 -- Auto download all images and only programs found in the "*plus/wdx/usr" directory
  (default setting)
• '+U' = 2 -- Auto download all images and all programs
• '+U' = 3 -- Auto download all images and all programs found in the system library (build 9182)
