library-file-spec

    The name of the library you want to create or modify. This
    parameter is required. If you do not specify a library file,
    you are prompted for one, as follows:

    _Library:

    No wildcard characters are allowed in the library file
    specification.

    If the file specification does not include a file type and if the
    command string does not indicate one, the LIBRARY command assumes
    a default type of .OLB, indicating an object library.

 input-file-spec[,...]

    The names of one or more files that contain modules you want to
    insert into the specified library. If you specify more than one
    input file, separate the file specifications with commas.

    The input file specification is required when you specify
    /REPLACE, which is the LIBRARY command's default operation, or
    /INSERT, which is an optional qualifier.

    When you use the /CREATE qualifier to create a new library, the
    input file specification is optional. If you include an input
    file specification with the /CREATE qualifier, LIBRARY first
    creates a new library and then inserts the contents of the input
    files into the library.
