Procedures and Functions:

    STREAM_$CLOSE (stream-id, status)
        Closes a stream.

    STREAM_$CREATE (pathname, namelength, access, concurrency, stream-id,
                    status)
        Creates an object (if the object does not already exist) and
        opens a stream to it.

    STREAM_$CREATE_BIN (pathname, namelength, access, concurrency,
                        stream-id, status)
        Creates a binary record-structured file (if the file does not
        already exist) and opens a stream to it.

    STREAM_$CREATE_HERE (pathname, namelength, access, concurrency,
                         loclen, locname, stream-id, status)
        Creates an object at the specified location and opens a
        stream to it.

    STREAM_$DELETE (stream-id, status)
        Deletes an object and closes the associated stream.

    STREAM_$FORCE_WRITE_FILE (stream-id, options, status)
        Forcibly writes a disk file open on the given stream.

    STREAM_$GET_BUF (stream-id, bufptr, buflen, retptr, retlen, seek-key,
                     status)
        Reads data from an object into a specified buffer.

    STREAM_$GET_CONDITIONAL (stream-id, bufptr, buflen, retptr, retlen,
                             seek-key, status)
        Reads a record if the record is available, otherwise
        sets the returned record length to zero.

    STREAM_$GET_EC (stream-id, stream-key, eventcount-pointer, status)
        Gets the eventcount address of the eventcount to be
        advanced upon any activity within the specified stream.

    STREAM_$GET_PRIOR_REC (stream-id, bufptr, buflen, retptr, retlen,
                           seek-key, status)
        Reads the previous record.

    STREAM_$GET_REC (stream-id, bufptr, buflen, retptr, retlen, seek-key,
                     status)
        Reads the next sequential record from an object.

    STREAM_$INQUIRE (input-mask, inquiry-type, attributes, error-mask,
                     status)
        Returns information about an object.

    STREAM_$OPEN (pathname, namelength, access, concurrency, stream-id,
                  status)
        Opens a stream to an existing object.

    STREAM_$PUT_CHR (stream-id, bufptr, buflen, seek-key, status)
        Writes data to an object without terminating
        the current record, if one exists.

    STREAM_$PUT_REC (stream-id, bufptr, buflen, seek-key, status)
        Writes data to an object and terminates the current record, if
        one exists.

    STREAM_$REDEFINE (stream-id, input-mask, attributes, error-mask,
                      status)
        Changes one or more attributes of an object that is open on a
        stream.

    STREAM_$REPLACE (stream-id, bufptr, buflen, seek-key, status)
        Writes data to an object without changing the
        length of the current record.

    STREAM_$SEEK (stream-id, seek-base, seek-type,
                  {seek-key|signed-offset}, status)
        Moves the stream position.

    STREAM_$TRUNCATE (stream-id, status)
        Writes EOF at the current stream position.
