Viewing the 13 digits held within a register is a pain, however. You could try some manual technique, but they would be very time consuming. If you hook the calculator up to a PC-100A or PC-100C printer, you can get a list of up to the first 10 significant digits in a register, but it won't list all thirteen.
Why then do you need to view up to the 13 digits? Well, quite a few programs put these extra storage digits to good use. On quite a few programs, you have to load a data card into the calculator that already has 13 digit constants to be stored into registers. This program will print out the 13 digit contents of each register. This program is a modification of a program that appeared in the May/June 1982 PPX Exchange by Markusson. This modification to that program first appeared in the TI PPC Notes V9N4P4, July/August 1984 by Gene Friel. It allows for user control of the starting register to be printed (like Markusson's original program) but also the ending register to be printed. For example, if you are going to run a program that requires 13 digit constants to be in memories 24 - 39, you can print ONLY those registers and show all 13 digits.
