Description of Problem
----------------------
Clause '13.3.2 Extended identifiers', second paragraph.
 The sentence is read as follows:
 
 "If a backslash is to be used as one of the graphic characters 
 of an extended literal, it must be doubled."
 
   

Proposed Resolution
-------------------
My proposal is to change the 'extended literal' to 'extended 
identifier' to reflect the sense of discussed subject, so the 
final sentence will read as follows:
 
"If a backslash is to be used as one of the graphic characters 
of an extended identifier, it must be doubled."
 
        

VASG-ISAC Analysis & Rationale
------------------------------

The submitter is correct.  This is an editorial error.

VASG-ISAC Recommendation for IEEE Std 1076-2002
-----------------------------------------------

In 13.3.2, the sentence 

  If a backslash is to be used as one of the graphic characters 
  of an extended literal, it must be doubled.

should be interpreted as

  If a backslash is to be used as one of the graphic characters 
  of an extended identifier, it must be doubled.


VASG-ISAC Recommendation for Future Revisions
---------------------------------------------

In 13.3.2, the sentence 

  If a backslash is to be used as one of the graphic characters 
  of an extended literal, it must be doubled.

should be replaced with

  If a backslash is to be used as one of the graphic characters 
  of an extended identifier, it must be doubled.
