Glad to contribute. I thought there was something strange about a 2007 post being remarkably up to date.

I'll post what I got of the code for the G+, and the issues I found (so far) in it. Lbl lines need to be on their own line, or the G+ freaks out with Arg Error, i.e.

Code:

'Errors out with Arg Error with the cursor pointing to X

Lbl 0 X=R=>Goto 4

'No Error

Lbl 0

X=R=>Goto 4

The same can be said where Isz/Dsz lines get combined with their next lines, except this time it's a Syn Error

Code:

Lbl 1 Isz S

Lbl 2 Dsz Y Deg

...

' should read

Lbl 1

  Isz S

...

Lbl 2

  Dsz Y

  Deg

...

Once I cured these small errors, I was able to get the program to complete, with a time not much different from the other 9750G+ result (1m47.6s). I was really puzzled about the apparent addition of a do-nothing command Deg to the Dsz Z, but without it, the program doesn't work, because the statement Y=0=>Goto 0 is being treated as the "Z<>0" portion of the Dsz command instead of the "Z=0" and the Y=0 never gets evaluated. Things unwind when the List 1[X] - List 1[Y] happens, and you can't have List 1[0] on the G+. That caused me to hunt around for a good while trying to find the bug when I'd simply removed the Deg (as it looks like a typo).

At that time, I took it as obvious, that the format of many test codes is not exactly what we see in the editor of the calculator.
I tried to make the test codes more readable, but maybe it was a little too much of the good. Sorry for the complications.

"Dsz Y Deg" is a litte bit faster than "Y-1->Y". Deg is used as NOP and is necessary in the case of Y=0 to suppress the skip.

is the 90+E practically a cg50 with micropython ?

Hi pier4r,
With the new software update 3.20, the CG50 also has the Python menu (MicroPython version 1.9.4, I think)
Cheers.

It's practically a CG50 with an LED for exam mode.

I wonder if the fx-CG50 can do Python as well since the 90+E is supposed to be the French version.

The version of the Cg50 being sold in WH Smith (a UK high St retailer) prior to lockdown mentioned Python, though it didn't specify which version (and never had any in stock).

Now that lockdown is easing, the version now being sold in WH Smith doesn't mention Python.

That could mean that they are selling older stock... Or just that the marketing guys don't want to sell the Cg50.

It's also conceivable that Python had to be withdrawn due to some vulnerability or exam restriction.

It's no big deal since OS 3.40 (available on Casio's website) includes Python.

Perhaps it's not worth mentioning because it is irrelevant for the UK syllabi.

Quote:It's also conceivable that Python had to be withdrawn due to some vulnerability or exam restriction.

Python is disabled in Exam mode, and as toml_12953 mentioned, the user can install it anyway.

I'd rather pay £123* for a Python that worked, than £123* + £300* for a PC that might possibly fix it.
(And, I like to encourage sales staff that try to sell calculators, rather than those that try to hide them... At least the Cg50 exists on the High St, even if it lacks Python there).

*Prices are approximate.

Check Ryman too. You may find it cheaper there (currently £99.99).

Thanks.
The price is cheaper there (though for me the shop is an extra 20 miles away). But yet again, no Python.
