RE: Calculator benchmark
SHARP PC-G850(V)(S): 107 keystrokes

Same number of keystrokes as the PC-E500(S) but one more for R. instead of F1 to run. The SHARP PC-G850(V)(S) has the same or similar keys (but no function keys) and similar BASIC.

SHARP PC-1403 to PC-1475: 118 keystrokes

An older series with the same or similar keys as the PC-E500(S), but with simpler BASIC, which has no impact on keying-in this simple program. However, [ENTER] is required after each pair of X,Y results are displayed (because all PC-14xx have a one-line LCD, except PC-1475 which has two lines. Thus adding 11 more keystrokes compared to the PC-E500(S).

Edit note: by comparison, the AREAD-based program for the PC-14xx series takes 111 keystrokes, here in full detail:

Code:
[MODE]                                  1    PRO mode 1"A"A.A[ENTER]                          8    1:"A"AREAD A 2"B"A.B[ENTER]                          8    2:"B"AREAD B 3P.[x^2]A+A-[ln]B,[ln][x^2]B[ENTER]    15    3:PRINT SQU A+A-LN B,LN SQU B [MODE]                                  1    RUN mode
Setup: 33
Code:

Execution: 78

Total score: 111

Total score is 110 when entering B first before A for the first entry pair. This avoids having to clear the error [CL] when B is zero.
