Hello Dave, After clearing flags 85 & 92 your example program worked exactly as described. Thank you E6 for you help and response. I will keep practicing as well as getting more referance material. Hopefully some day I will understand why you up-to-date HP'ers say RPL rather than RPN. Even the skimpy documentation uses RPL. Also I hope to eventually learn the purpose of flags 85 & 92.
