/IMAGE_FILE=file-spec
       /NOIMAGE_FILE (default)

    By default, CLBUILD does not produce a compiled command
    definition file. In order to produce a compiled command
    definition file, the file to produce must be specified using the
    /IMAGE_FILE qualifier. Note that the logical name PMDF_COMMAND_
    DATA may be specified as the image file-spec, if the goal is to
    produce a compiled version of the main PMDF command definition
    file, PMDF_COM:PMDF.CLD.
