P. [. . . ] No code is shown for program line 000, since no regular instruction is stored there. Identifying Instructions in Program Lines Each key on the hp 12c platinum keyboard -- except for the digit keys 0 through 9 -- is identified by a two-digit "keycode" that corresponds to the key's position on the keyboard. The first digit in the keycode is the number of the key row, counting from row 1 at the top; the second digit is the number of the key in that row, counting from 1 for the first key in the row through 9 for the ninth key in the row and 0 for the tenth key in the row. Thus, when you keyed the instruction b into program memory, the calculator displays a line number and a keycode 004, 25 This indicates that the key for the instruction in program line 004 is in the second row on the keyboard and is the fifth key in that row: the b key. When you keyed the instruction + into program memory, the calculator displays a line number and keycode as 007, 40 This indicates that the key for the instruction in program line 007 is in the fourth row on the keyboard and is the tenth key in that row: the + key. When you keyed the digit 5 into program memory, the keycode displayed was only the digit 5.

Instruction gÒ ?=0 gi000 Keycode nnn, 43 26 0 nnn, 44 40 nnn, 43, 33, 000 Displaying Program Lines Pressing fs to set the calculator from Run mode to Program mode displays the line number and keycode for the program line to which the calculator is currently set. Occasionally you'll want to check several or all of the instructions stored in program memory. The hp 12c platinum enables you to review program instructions either forward or backward through program memory: Pressing Ê (single step) while the calculator is in Program mode advances the calculator to the next line in program memory, then displays that line number and the keycode of the instruction stored there. Pressing gÜ (back step) while the calculator is in Program mode sets the calculator back to the previous line in program memory, then displays that line number and the keycode of the instruction stored there.

Keystrokes (ALG mode) fs Display 000, Sets calculator to Program mode and displays current line of program memory Ê Ê 001, 002, 30 2 Program line 001: Program line 002: digit 2. Pressing gÜ does the reverse: Keystrokes (RPN mode) gÜ gÜ Display 001, 000, 36 Program line 001. Program line 000. Keystrokes (ALG mode) gÜ gÜ Display 001, 000, 30 Program line 001. Program line 000.

Press Ê again now, but this time hold it down until program line 007 is displayed. . (Release Ê) 007, 40 Program line 007 Keystrokes (ALG mode) Ê Display 001, . . (Release Ê) 007, 36 Program line 007 Program line 007 contains the last instruction you keyed into program memory. However, if you press Ê again, you'll see that this is not the last line stored in program memory: Keystrokes Ê Display 008, 43, 33, 000 Program line 008 As you should now be able to tell from the keycodes displayed, the instruction in program line 008 is gi000.

This i000 instruction -- as its name implies -- tells the calculator to "go to" program line 000 and execute the instruction in that line. Although line 000 does not contain a regular instruction, it does contain a "hidden" instruction that tells the calculator to halt program execution. Thus, after each time the program is run, the calculator automatically goes to program line 000 and halts, ready for you to key in new data and run the program again. (The calculator is also automatically set to program line 000 when you press fs to set the calculator from Program mode to Run mode or when fCLEARÎ is pressed in run mode. ) The i000 instruction was already stored in line 008 -- in fact, in all program lines -- before you keyed in the program. If no instructions have been keyed into program memory, if Continuous Memory is reset, or if fCLEARÎ is pressed (in Program mode), the instruction i000 is automatically stored in program lines 001 through 008. As you key each instruction into program memory, it replaces the i000 instruction in that program line. If your program should consist of exactly eight instructions, there would be no i000 instructions remaining at the end of program memory.
