Example

   CMS> MODIFY LIBRARY/REFERENCE_COPY=[WORK.REFCOPY] "current 
   test area"
   %CMS-S-MODIFIED, library [WORK.CODELIB] modified

     This command establishes the reference copy directory
     [WORK.REFCOPY] for the current CMS library. In addition, to
     update the reference copy directory, an element must be set to
     /REFERENCE_COPY. Thus, if these two conditions are met, each
     transaction that creates a new main line element generation
     also updates the reference copy directory.
