\\fls0\root.bin
\\fls0\FOLDER\file.bin
When I have a PROGRAM.g1m in SMEM:
16>Dim List 1 Load("/root.bin")>List 1 Load("/DATA/file.bin)>List 1This works fine.
However, when I have this program in Main Mem, it fails on line 3 (load from folder)
I put most programs in Main Mem to reduce flash wear and I can also recover programs if I accidentally delete them.
To resolve this I used BFile syscalls, but that is a bit annoying as it leaks file handles sometimes because I forget a BFile_Close syscall somewhere.

If I create a list with N>Dim List 1, is it guaranteed that List 1 is a contiguos memory area of N elements? And when exactly does C.Basic move pointers around? I noticed that clearing a list/mat/vec sometimes causes reallocation of other lists/vecs/mats, even creating strings can cause that (probably because Mat r has to be reallocated). This cause headaches because some programs tend to break because they hold a reference to a list while that has already been moved. Is it possible to pin/fix a list in place? Maybe something like
{1,2,3,4}>Fixed List 1.L &List 1>A 16>Dim Fixed List 2.B &List 2>B 'A, B still point to the same location, even if other things have been allocated/deallicated in the meantime SysCall(_SCmemcpy,B,A,16) '_SCmemcpy is set to 0x1DD0 or 0xACF depending on calculator

Thanks for the update. FKeyMenu is finally customizable simply by numerical expressions instead of bunch of Ifs
I noticed a few bugs in the new version:
 In FX version, the cursor in file manager does not fully cover the current line.
 Pressing
while Hist popup is shown in C.Basic catalog goes back to program editor instead of only closing the popup.
Also, thanks for uploading more old C.Basic versions on eGadget! But it seems like CBASIC099o1.zip in your archive is corrupted. (^^;

Dear Sentaro, I am happy to see you again here. I worked with C.Basic all the time. Half a year ago, I switched to the most uptodate model Graph 90+E, which is a close sibling to the CG50. I love the white housings, where I can read the symbols easier.
Using it I detected, that battery life is much longer.
I update C.basic today.

Dear sentaro and all, my most advanced project is the simulation of an open cluster with the calculator. If you let a bunch of stars do what they want, you see interesting effects. Which occur in reality too
 development of a dense core and a halo
 some of the stars escape
 you get double stars, which generate energy = velocity for the other stars
Double stars are a remarkable numerical problem, because I have a time step control. The simulation of double stars requires small time steps.
I changed my comments into English, but I let the changed version not run. May be you have to eliminate tiny problems lie a missing ' or so.
The program recommends 50 stars, but I worked with larger numbers too.
The first such calculations were done by Sebastian Hoerner starting around 1951 with very few bodies. Sverre Aarseth dedicated all of his professional life to that problems. His Fortran programs are very advanced and freely available.
Here is a wiki site to the problem.
https://en.wikipedia.../Nbody_problem
~
If you run the program you get a graph with the traces of the stars. In the top line is given:
time (ahead the .)number of escaper (after the .)Wkin/Wpot, that is the relation kinetic to potential energy

Well, I managed to fix the CBASIC099o1.zip using WinZip and successfully retrieved most of its files. Suprisingly the g1a file is also saved and works as usual. Some of its source files are lost, but anyway I uploaded it on my Mediafire driver.
I am working on C.Basic version documentation, so I have to trace every C.Basic version you have released and see what exactly you have changed in each of them, as well as making some sort of table like this : https://imgur.com/a/vXixVMC (credits to Minecraft Wiki)

wow, this program is amazing although i wont be able to test it yet, I am amazed by how much effort is still put into making these prograams!

It changes the pocket calculator into a real programming system.
