Dear DDLm participants, Here is a proposed text for a COMCIFS vote. I will mark up the text and get Brian to post it on the IUCr website following your editorial comments. =========== We propose that Change 7 in the current draft is replaced by the following text: Change 7 - NEW The ASCII """ sequence (alternatively ASCII ''') delimits the beginning of a string that may contain any printable character and whitespace, including embedded <eol> characters, and is terminated by the first subsequent """ sequence (alternatively '''). The string can contain separable " and "" characters, (alternatively ' and ''). Clearly, the string within cannot contain an ASCII """ (or alternatively ASCII '''). For example """He said "His name is O'Hearly".""" '''In {\bf \TeX} the accents are \' and \".''' The string values are, He said "His name is O'Hearly". and In {\bf \TeX} the accents are \' and \". Two speqial character sequences are defined: <backslash><backslash> and <backslash><eol>. <backslash><backslash> represents a single <backslash> character. <backslash><eol> sequences are removed from the string completely. For example: """This string contains a single \\ and \ no newline""" has string value This string contains a single \ and no newline and the string """An embedded ""\ " triple-quoted string ""\ " is easy to produce""" has string value An embedded """ triple-quoted string """ is easy to produce =============== -- T +61 (02) 9717 9907 F +61 (02) 9717 3145 M +61 (04) 0249 4148 _______________________________________________ ddlm-group mailing list ddlm-group@iucr.org http://scripts.iucr.org/mailman/listinfo/ddlm-group
