With regard to the HP48 "Hex Editor" or Memory Scanner, as others refer to it, there is a nice full description of it on pages 99-100 of Jim Donnelly's book "The HP48 Handbook". Also, pages 96 thru 98 describes most of the other interactive self tests and combination-key-press features, including the System Halt Log which is accessed by the WSLOG function. Jim's book is available from EduCalc for $19.95. This book is highly recommended. Educalc may be reached at 800-677-7001. Jake Schwartz
