[. . . ] (Press or while the label is while the label is displayed. ) while the label is displayed. ) See the checksum associated with a given program segment. (Press . ) The catalog shows you how many bytes of memory each labeled program segment uses. The programs are identified by program label: where 67 is the number of bytes used by the program. Clearing One or More Programs To clear a specific program from memory 1. Press program. { . } and display (using and ) the label of the 2. Press to cancel the catalog or to back out. 1220 Simple Programming To clear all programs from memory: 1. Press to display program lines (PRGM annunciator on). Press Clearing all of memory ( The Checksum The checksum is a unique hexadecimal value given to each program label and its associated lines (until the next label). This number is useful for comparison with a known checksum for an existing program that you have keyed into program memory. If the known checksum and the one shown by your calculator are the same, then you have correctly entered all the lines of the program. To see your checksum: 1. Press { } for the catalog of program labels. Display the appropriate label by using the cursor keys, if necessary. Press and hold For example, to see the checksum for the current program (the "cylinder" program): Keys: (In RPN mode) { } (hold) Display: Description: Displays label C, which takes 67 bytes. Checksum and length. If your checksum does not match this number, then you have not entered this program correctly. You will see that all of the application programs provided in chapters 15 through 17 include checksum values with each labeled routine so that you can verify the accuracy of your program entry. In addition, each equation in a program has a checksum. See "To enter an equation in a program line" earlier in this chapter. Simple Programming 1221 Nonprogrammable Functions The following functions of the HP 33s are not programmable: { { , , , } } , label nnnn Programming with BASE You can program instructions to change the base mode using . These settings work in programs just as they do as functions executed from the keyboard. This allows you to write programs that accept numbers in any of the four bases, do arithmetic in any base, and display results in any base. When writing programs that use numbers in a base other than 10, set the base mode both as the current setting for the calculator and in the program (as an instruction). Selecting a Base Mode in a Program Insert a BIN, OCT, or HEX instruction into the beginning of the program. You should usually include a DEC instruction at the end of the program so that the calculator's setting will revert to Decimal mode when the program is done. An instruction in a program to change the base mode will determine how input is interpreted and how output looks during and after program execution, but it does not affect the program lines as you enter them. Equation evaluation, SOLVE, and FN automatically set Decimal mode. 1222 Simple Programming Numbers Entered in Program Lines Before starting program entry, set the base mode. The current setting for the base mode determines the base of the numbers that are entered into program lines. The display of these numbers changes when you change the base mode.
