    Format

      SET LIBRARY   directory-spec[, . . . ]

1  –  Qualifiers

1.1    /AFTER

       /AFTER[=library-spec]

    Instructs SCA to insert the new library or libraries into the
    list of active SCA libraries after the library you specify as
    the qualifier value. If you do not specify a value, SCA adds the
    library or libraries to the end of the list.

1.2    /BEFORE

       /BEFORE[=library-spec]

    Instructs SCA to insert the new library or libraries into the
    list of active SCA libraries before the library you specify as
    the qualifier value. If you do not specify a value, SCA adds the
    library or libraries to the beginning of the list.

1.3    /LOG

       /LOG (D)
       /NOLOG

    Indicates whether SCA reports the resulting list of active SCA
    libraries.

2  –  Parameter

 directory-spec[, . . . ]
    Specifies one or more directories, each of which comprises a
    separate SCA library. The list of libraries you specify replaces
    the current list of active libraries unless you specify an /AFTER
    or /BEFORE qualifier.
