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 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.
For example, to display the first two lines of the program now stored in program
memory, set the calculator to Program mode and press Ê twice:

Pressing gÜ does the reverse:

If either the Ê key or the Ü key is held down, the calculator displays all of the
lines in program memory. Press Ê again now, but this time hold it down until
program line 07 is displayed.
