 code

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference
    SORT/MERGE statistic code. The code argument is the address of
    a longword containing the code that identifies the statistic
    you want returned in the result argument. The following table
    describes the values that are accepted.

    Note: The high-performance Sort/Merge utility currently supports
    only the following subset of these values: SOR$K_REC_INP, SOR$K_
    REC_SOR, SOR$K_REC_OUT, SOR$K_LRL_INP.

    Code             Description

    SOR$K_IDENT      Address of ASCII string for version number
    SOR$K_REC_INP    Number of records input
    SOR$K_REC_SOR    Records sorted
    SOR$K_REC_OUT    Records output
    SOR$K_LRL_INP    Longest record length (LRL) for input
    SOR$K_LRL_INT    Internal LRL
    SOR$K_LRL_OUT    LRL for output
    SOR$K_NODES      Nodes in sort tree
    SOR$K_INI_RUNS   Initial dispersion runs
    SOR$K_MRG_       Maximum merge order
    ORDER
    SOR$K_MRG_       Number of merge passes
    PASSES
    SOR$K_WRK_ALQ    Work file allocation
    SOR$K_MBC_INP    Multiblock count for input
    SOR$K_MBC_OUT    Multiblock count for output
    SOR$K_MBF_INP    Multibuffer count for input
    SOR$K_MBF_OUT    Multibuffer count for output

    Note that performance statistics (such as direct I/O, buffered
    I/O, and elapsed and CPU times) are not available because user-
    written routines may affect those values. However, they are
    available if you call LIB$GETJPI.

 result

    OpenVMS usage:longword_unsigned
    type:         longword (unsigned)
    access:       write only
    mechanism:    by reference
    SORT/MERGE statistic value. The result argument is the address
    of a longword into which SORT/MERGE writes the value of the
    statistic identified by the code argument.

 context

    OpenVMS usage:context
    type:         longword (unsigned)
    access:       modify
    mechanism:    by reference
    Value that distinguishes between multiple, concurrent SORT/MERGE
    operations. The context argument is the address of a longword
    containing the context value. When your program makes its first
    call to a SORT/MERGE routine for a particular sort or merge
    operation, the context longword must equal zero. SORT/MERGE
    then stores a value in the longword to identify the operation
    just initiated. When you make subsequent routine calls for the
    same operation, you must pass the context value supplied by
    SORT/MERGE.
