If you're missing the CATALOG function of the HP28, there's a nice program which comes on the Serial Interface Kit disk called USAGE which at least puts back the USE key from the HP28 CATALOG function. The program object is about 1300 bytes. If a list is entered on stack level one containing a single element - the function in question - and USAG is pressed, the machine return one or more screenfuls of information about stack inputs, whether the opera- tion is integrable, differentiable and has an inverse. My only wish is that this function could have worked like the HP28's version, allowing us to step through all the functions in the HP48 and stop on the one which we desired. Perhaps also single-ALPHA key entry points into the table as well? Jake Schwartz
