All, We need to update the c.xml and isocpp.xml syntax files to include size_t as a type. A simple addition of the following in the type section is all that is needed: <item> size_t </item> Nothing could be easier. Let me know if you think a bug/feature request is needed or if somebody can take it from here. Make code much nicer to read... -- David C. Rankin, J.D.,P.E.
