    PDL Changes shows the changes made to the product description
    language (PDL) for the POLYCENTER Software Installation
    utility.

    Table 5-1 PDL Changes

    Statement          Description

    execute upgrade    New statement.
    execute            Modified to execute on a reconfigure
    postinstall        operation.
    file               Refinements made to their conflict detection
    module             and resolution algorithms. For example, when a
                       file from the kit contains the same non-zero
                       generation number as the same file already
                       installed, the file from the kit is selected
                       to replace the file on disk. Previously,
                       in this tie situation, the file on disk was
                       retained to resolve the conflict.
    bootstrap block    Obsolete. However, the utility will continue
    execute release    to process these statements in a backward
    patch image        compatible manner to support existing kits
    patch text         that might have used them.

    Function           Description

    upgrade            Enhanced to fully support version range
                       checking.
