Aritm - A s/w for training mental calculation on CASIO fx-9860GII

[M.O.B. i L.]

I have developed a mental calculation training program called Aritm.
It's based on a program I developed in C for MS-DOS in 1992 but more
directly on my TI-BASIC-version from 2010. This version is for CASIO
fx-9860GII but it might work on other models such as fx-9750GII.

You can download the program here:
http://www.df.lth.se/~mikaelb/casio/fx-9860gii/mob-i-l/. Aritm for Casio
and TI and some other systems is free open source software (FOSS) with
the well known license GPLv3+. You run ARITM but the file also contains
some subprograms beginning with ZA that also are necessary.

The Texas Instruments TI-82/TI-82 STATS/TI-83/TI-83 Plus/TI-84
Plus-version is here and it has documentation but the program is rather
self-explanatory: http://www.df.lth.se/~mikaelb/ticalc.html#aritm.

I developed the program in the Casio-BASIC programming language in the
editor in the communication program FA-124 2.00 and on the graphing
calculator CASIO fx-9860GII with OS 02.01.0200. The program uses the
command Menu and the function RanInt# and it stores its data in a list
that can be up to 590 floating point elements long. I know the the
program could be more optimized but I struggled with the editor in
FA-124 and I didn't want to use strings since that would make porting to
older models more difficult. The editor in FA-124 2.00 seems to
introduce strange bugs, e.g. RanInt# is converted to RanBin# in the
editor if you import code and list indices (e.g. [J]) sometimes becomes
tokenized on the calculator and produces errors when you run the code.
This only occurs if you edit the code in FA-124. If you just import it
and then transfer it there should be no problems provided you use the
latest versions of FA-124 and Casio OS 2.

Aritm could be ported to other models such as Algebra FX 2.0 Plus and
fx-9750G. I don't have a link-cable for Casio and have to transfer the
program through the fx-9860GII to the other calculator models and so far
I've only succeeded in transferring it to fx-9750G and not to Algebra FX
2.0 Plus, CFX-9800G or fx-7700GE. Aritm cannot run on the fx-9750G as it
is now.

If someone wants to help convert Aritm to other calculator models and
distribute the program according to GPLv3+ that would be great. If one
cannot use lists of length 590 one might use matrices and the technique
I use in the TI-82-version (since lists on TI-82 can only be 99 elements
long).

There are some hacks you can do to the program e.g. introduce new
exercises such as multiplication with the 11 and 12 tables.
