Consider: `define DFT_IGNORE(arg) \ ... \ `define ATTR \ ... \ `endif This is intended to be a 1-line text macro definition nested within a multi-line macro definition. The question here is whether the backslash after "`define ATTR" is considered to be continuing the multi-line macro definition of `DFT_IGNORE and "`define ATTR" is a 1-line macro, or whether the backslash is considered to continue a multi-line macro definition of ATTR. We favor the 1st interpretation. We think this is supported by the text in 1364-2005: "The macro text can be any arbitrary text specified on the same line as the text macro name. If more than one line is necessary to specify the text, the newline shall be preceded by a backslash (\). The first newline not preceded by a backslash shall end the macro text. The newline preceded by a backslash shall be replaced in the expanded macro with a newline (but without the preceding backslash character)." This allows 1-line macro definitions to be embedded within multi-line macro definitions, but does not allow to nest one multi-line macro definition within another. That will in any case require an enhancement. Shalom Shalom Bresticker Intel Jerusalem LAD DA +972 2 589-6852 +972 54 721-1033 I don't represent Intel
