Section 8: Programming Basics 109 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. Instruction Keycode gÒ nnn, 43 26 ?=0 nnn, 44 40 0 gi000 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: z 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. z 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.
