DO versions

You can check in a derived object as a version of an element, creating a DO version. Other versions of such an element can also be, but need not be, derived objects.

A DO version behaves like both a version and a derived object:

• You can use its version ID to reference it as both a VOB database object and a data file.
• You can apply a version label to it and use that label to reference it.
• You can display its configuration record with catcr or compare the CR to another with diffcr.
• A clearmake build can wink it in if the element is located at the same path name where the DO was originally built.
• You can wink it in with a winkin command.
• The describe command lists it as a derived object version. (The lsdo command does not list it at all.)
