Description

   The PRODUCT command is used to install, remove, or display
   products which are part of the OpenVMS environment.  The PRODUCT
   command is the interface to the POLYCENTER Software Installation
   (PCSI) utility.

   To install products, patches, or mandatory updates, use the
   PRODUCT INSTALL command.

   To uninstall complete products, including any patches or
   mandatory updates that might have been applied to them, use the
   PRODUCT REMOVE command.

   To uninstall patches or mandatory updates while still retaining
   the original product that was installed, use the PRODUCT UNDO
   PATCH command. However, to use PRODUCT UNDO PATCH, you must have
   created and retained recovery data sets for these patches. (By
   default, the PRODUCT INSTALL command creates a recovery data set
   when patch kits are installed.)

   For more information about the use of recovery data sets, see the
   description of the PRODUCT UNDO PATCH command.
