       /CONCATENATE
       /NOCONCATENATE

    Qualifier type:  qualifier

    Supported file   Local (RMS) (/CONCATENATE only) and remote files
    types:

    This qualifier controls whether multiple input files create corre-
    sponding multiple output files or create a single output file
    containing the concatenated contents of all the input files.
    Concatenation, which is the default, involves combining multi-
    ple input files (in their input order) into a single output file.
    For concatenation, all the input files must have identical file
    organization, record format, and record attributes. Creating mul-
    tiple output files, which requires local input files, requires the
    /NOCONCATENATE qualifier.

    Default action:  /CONCATENATE; The output file bears the name of
                     the first input file.
