Herbert, Yes! I discovered the problem and was just going to write. In Uwe's example I saw, "use amsmath 1". In my file it was "use amsmath 0". Changed my file and it compiles. It was not that I forget; I didn't know to do add the amsmath package in the preamble. This was not "intuitive" for me. :-) Whew! This was a major stumbling block and I learned a lesson not soon forgotten: use the amsmath package if there will be equations in the text. Many, many thanks to all of you, Rich -- Dr. Richard B.
