ISO/IEC JTC1/SC22/WG20  N085


	Title: Extended identifiers

	Source: WG20

	Date: 1992-04-23

	Users of programming languages and environments require that
	related standards would allow identifiers such as variable
	names, functions and procedures, to contain characters beyond
	those in the ISO/IEC 646 repertoire.

	WG20 will propose extention characters, and will not otherwise
	discuss the existing rules for these identifiers.

	WG20 will propose character attributes, such as:

	    1 - allowable in identifiers
	    2 - lowercase/uppercase/no case
	    3 - shifted character (possibly nonexistent)

	The proposal for the allowable characters in identifiers will
	include those characters that can be used in words of natural
	languages, such as alphabetic characters with diacritic marks,
	syllabic and ideographic characters.

	These attributes are fixed.

	WG20 will describe portability aspects related to the proposed
	extensions and encourages discussion on its proposals and
	descriptions.
