Thanks for all those who responded to my previous question. Now a new, unrelated one. I have a function which uses the FindRoot function. Occasionally FindRoot fails to converge, as there really is no solution. To trap this occurence, I have wrapped the call to FindRoot in the Check[] function. If an error in FindRoot occurs, I trap it, and substitute a Null solution into the list I am generating. Everything works beautifully so far. However, I don't want Mathematica to print error messages all over my screen every time this occurs!! I'm dealing with the problem!! However, the manual says that Check[] will not trap errors that have been disabled with Off[]. So, it seems there is no way to silently trap an error message. Is this true? Paul.
