Just my 2c: the keystrokes for the Casio fx-cg50 aren't the same as Casio fx-9750GIII (I own the former, not the latter). There is no Shift Setup F2 to switch to line I/O mode (it selects COORD instead) and EXE works differently. Use Shift Prgm and keep the FN menu to enter Prgm symbols. AEXE inserts a newline/carriage return [NL] symbol for the next statement:

Code:

Shift Prgm                      Activate Prgm FN keys
F4 -> Alpha A EXE               Enter: ?->A[NL] (input A)
F4 -> Alpha B EXE               Enter: ?->B[NL] (input B)
Alpha A x^2 + Alpha A -
ln Alpha B F5                   Enter: A^2+A-ln B Triangle   (display first answer)
ln Alpha B x^2                  Enter: ln B^2   (display second answer)

Program: 27 keystrokes. Then EXIT EXIT EXE to run the program.

Execution: all 24 values must be entered (99) each with EXE (24), then another 12 EXE to display the second value, and 12 EXE + 11 EXE to rerun = 158 keystrokes, plus the 3 to exit the editor and run the program. Because there is no loop in the program, execution requires one more EXE after the second display to rerun the program.

Adding a loop:

Code:

Shift Prgm                      Activate Prgm FN keys
F3 F1 1 EXE EXIT                Enter: Lbl 1[NL]
F4 -> Alpha A EXE               Enter: ?->A[NL] (input A)
F4 -> Alpha B EXE               Enter: ?->B[NL] (input B)
Alpha A x^2 + Alpha A -
ln Alpha B F5                   Enter: A^2+A-ln B Triangle   (display first answer)
ln Alpha B x^2                  Enter: ln B^2   (display second answer)
F5                              Enter: Triangle
F3 F2 1                         Enter: Goto 1

Program: 36 keystrokes.

Execution: 147 keystrokes (99+24+24) plus the 3 (EXIT EXIT EXE) to exit the editor and run the program.

Casio fx-CG50: 186 keystrokes.
