Description

   The CONVERT LIBRARY command creates a copy of an existing CMS
   library and converts the copy for use with this version of
   CMS. Libraries created with CMS Version 3.0 do not need to be
   converted.

   To convert a library, you must first create an empty directory
   to contain the new, converted library. Conversion maintains
   everything in your existing library, including the reference
   copy directory. After the library is converted, CMS automatically
   executes the VERIFY/REPAIR command to ensure that any existing
   reference copy directory is valid and current.

   The CONVERT LIBRARY command causes an unusual occurrence to be
   logged in the history file.
