9、. The work of developing International Standards is carried out through IS0 Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set up has the right to be represented on that Committee. International organizations, governmental and non-governmenta
10、l, in liaison with ISO, also take part in the work. Draft International Standards adopted by the Technical Committees are circulated to the Member Bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard IS0 2047 was drawn up by Technical Comm
11、ittee ISO/TC 97, Computers and information processing, and circulated to the Member Bodies in December 1972. It has been approved by the Member Bodies of the following countries : Belgium Ireland Brazil Italy Canada Japan Czechoslovakia Mexico Denmark New Zealand Egypt, Arab Rep. of Poland France Ro

13、mation processing - Graphical representations for the control characters of the 7-bit coded character set 1 SCOPE This International Standard specifies graphical representations of the control characters of columns 0 and 1 of the IS0 7-bit coded character set for information interchange (IS0 646). I
14、t also provides graphical representations for the normally non-printing character SPACE (position 2/O of the Code Table) and for the character DELETE (position 7/15 of the Code Table). Two modes of representation are given in this International Standard : - a set of specific symbols where a single c
15、haracter is required for the graphical representation of each of these normally non-printing characters; - a set of alphanumeric representations comprising two characters derived from the abbreviations used in the IS0 7-bit table. 2 FIELD OF APPLICATION These graphical representations are intended f
16、or use for display of control characters on devices when the graphical representation of these normally non-printing characters is required. Among the devices included are paper tape punches, printers and CRT equipment. Various areas of use are possible; for example, monitoring and diagnostic applic
17、ations. The precise font design is not part of this International Standard. The implementation of some of the symbols does not imply that the whole set should be available. Each alphanumeric representation is to be considered as a single symbol. It may occupy either one or more positions on a printe
18、d or displayed line depending on the implementation. 3 REFERENCE IS0 646, 7-bit coded character set for infocmation processing interchange. 1 IS0 2047-1975 (El 4 REPRESENTATIONS Position in the 7-bit set table 010 011 012 013 014 015 016 017 Set table name NUL TCI TG TG TC4 TG TG BEL Meaning NUll St
