Section 8: Programming Basics 91 Identifying Instructions in Program Lines Each key on the hp 12c 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. The keycode for each digit key is simply the digit on the key. Thus, when you keyed the instruction b into program memory, the calculator displayed 04- 25 This indicates that the key for the instruction in program line 04 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 displayed 07- 40 This indicates that the key for the instruction in program line 07 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. Since keystroke sequences beginning with f, g, ?, :, and i are stored in only one program line, the display of that line would show the keycodes for all the keys in the keystroke sequence.
