status_block_address

    OpenVMS usage:vector_longword_unsigned
    type:         longword (unsigned)
    access:       write only
    mechanism:    by reference
    The conversion statistics. The status_block_address argument is
    the address of a variable-length array of longwords that receives
    statistics about the conversion.

    You can request conversion statistics using zero-based, symbolic
    offsets (CONV$K_) into the variable-length array of longwords
    that contains the statistics. The array is defined as a structure
    (CONV$STATISTICS) of named longwords (CONV$L_) to support access
    by high-level progamming languages.

    Conversion Statistics Array lists the array elements by number
    and by symbol. The first element specifies the number of
    statistics to return by array order. For example, if you assign
    the symbol CONV$L_STATISTICS_COUNT the value 2, the routine
    returns the statistics from the first two statistics elements:

    o  Number of files converted

    o  Number of records converted

 flags

    OpenVMS usage:mask_longword
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference
    Flags (or masks) that control how the CONV$PASS_FILES fdl_
    filespec argument is interpreted and how errors are signaled. The
    flags argument is the address of a longword containing control
    flags (or a mask). If you omit the flags argument or specify
    it as zero, no flags are set. The flags and their meanings are
    described in the following table:

    Flag             Function

    CONV$V_FDL_      Interprets the fdl_filespec argument supplied
    STRING           in the call to CONV$PASS_FILES as an FDL
                     specification in string form. By default, this
                     argument is interpreted as the file name of an
                     FDL file.
    CONV$V_SIGNAL    Signals any error. By default, the status code
                     is returned to the calling image.

    By default, an error status is returned rather than signaled.

 callback_routine

    OpenVMS usage:procedure
    type:         procedure value
    access:       read only
    mechanism:    by reference
    Name of a user-supplied routine to process the statistics
    information. The callback_routine argument is the address of
    the procedure value of a user-supplied routine to call at the
    completion of each key load.
