However, in MMLthe output of a decimal fraction of hours, minutes, or seconds is not utilized in the header.Time representations are based upon the 24-hour timekeeping syste
3、m. The sequencing of time elements shall befrom high order to low order (left to right): hours, minutes, seconds. The hour shall be represented by a two-digitdecimal number ranging from 00 up to and including 23. The minute shall be represented by a two-digit decimalnumber ranging from 00 up to and
4、including 59. The second shall be represented by a two digit decimal numberranging from 00 up to and including 59.Examples:Hours, minutes 1225 or 12:25Hours, minutes, seconds 122501 or 12:25:012.2.5 Additional header informationAdditional header information is general information which has no relati

6、hich contains information unique to the event which caused theoutput.2.4 Additional informationAdditional information is general information related to the output, e.g.: type of output e.g., maintenance, statistics. This is not the same as identification of output, (see 2.6), output recipient identi
7、fication.2.5 Command referenceA command reference supplies a command sequence number when needed in output outside dialogue as areference to a previous input. In addition to the command sequence number it may also include clarifying text. It alsomay appear in dialogue procedures (see Recommendation
8、Z.317).2.5.1 Clarifying textClarifying text is a set of information units used to make the purpose and contents of the output more clear tothe reader. Several clarifying texts could appear in an output.2.6 Identification of outputIdentification of output provides a unique identity for an output in a
9、 systems repertoire of outputs. Therefore, itcould be used as a reference to the explanation of the output in a manual.2.7 Text blockA text block is any combination of clarifying texts, variable texts, parameter name defined parameters and/ortables which gives information wherever it is needed or re
10、quested. For VDT applications this may be a displayed form.Fascicle X.7 - Rec. Z.316 32.8 TableA table is an ordered presentation of interrelated information.Clarifying text within a table can be used as labels to each column contained within the table. Where a tablename or additional information as
11、sociated with the table is required the clarifying text appearing at the beginning of thetable in the syntax diagram of 3.8 could be used.When parameter name defined parameters are used to label columns each parameter should be complete, i.e.contain a parameter value (see Recommendation Z.315).2.8.1
12、 New lineNew line is a character combination necessary to reset an output device to the beginning of a new line. It isrecognized that the character combination is device dependent but can contain the characters CR (carriage return) andLF (line feed). No syntax diagram is shown.2.9 End of outputAn en
13、d of output is an indication that an output is finished.2.10 Comments in outputThe purpose of a comment in output is as for clarifying text (see 2.5.1) with the exception that the syntax is asfor comment in input so that it may be discarded during a subsequent re-input. No syntax diagram is shown.3
