1    /SPM_PROCESS_ID

       /SPM_PROCESS_ID=(process-id[,...])

    Merges the specified SPM data files. Each process-id parameter
    must be a valid OpenVMS process identification number, specified
    as a hexadecimal number. You may omit the leading zeros. Each
    collection of PC data is assigned a RUN_NAME identifier of
    the form SPM_n, where n is the OpenVMS process identification
    number that you specify in the process-id list. The data must be
    collected for the image of the currently open data file. A list
    of more than one number must be enclosed in parentheses. If you
    omit this qualifier, the Analyzer assumes that all of the files
    are PCA performance files.

2    /ANC

    For PCA data files with identical image names, image identifiers,
    link times and link identifiers; PCA writes all ANC (acceptable
    non-coverage) information to the coverage-set table in the output
    file.

    For PCA data files with identical image names and different image
    identifiers, link times or link identifiers; PCA writes only ANC
    (acceptable non-coverage) information from the input PCA data
    file to the coverage-set table in the output file which can be
    validated by the codepath data in both the input and output PCA
    data files.

    /ANC and /SPM_PROCESS_ID cannot be used together in the same
    command. The /ANC qualifier can only be used when merging PCA
    performance data files.

3    /SINCE

       /SINCE="time-spec"
       /BEFORE="time-spec"

    Sets the lower and/or higher limits on the collection times of
    the SPM data being merged. These optional qualifiers can only be
    specified together with the /SPM_PROCESS_ID qualifier. The time-
    spec parameters must be enclosed within double quotation marks ("
    ") and must be valid OpenVMS absolute date/time specifications,
    as described in the DCL Concepts manual.
