In fact, the Wikipedia article (or one referenced by it) also discusses cases where thread safety does not necessarily imply reentrant. So you are in agreement with Wikipedia there. However, that is a completely different logical supposition than the one I stated above. Wikipedia states that both suppositions are true. To disprove the original supposition you must find an example where a routine is reentrant (following Wikipedia's definition of that) but not thread safe. Alan __________________________ Alan W.
