Hi again,
I'm still experimenting with Pascal code. Displaying text and graphics, reading the keyboard are OK. I've never needed any asm code. I feel ready to write great application programs purely and simply with Turbo Pascal

However, Most of the file handling statements/commands are behaving abnormally on the AFX. I guess there are many virtual disk drives in the unit. Some of them are read only and some are not.

Anybody with any (even tiny) information about these drives are fullheartedly welcome!! Pleaze..

Thanx in advance.

Well I know nothing of
how to use pascal on the calc but the flash is split in 7 drives
(L-Q & A) and the ROM has drives B-K. They are all read only at least
for any standard progrmming interface. if you want to write to the flash
to them you have to use assembler to communticate directly with the flash.

Hi,
Thanks for the info huhn. I want to know something: most asm/C programming sites about AFX feature file management utilities. If you can access file processing routines of AFX DOS via asm, then you can do just the same using C/C++ or Pascal. Can't Turbo C code access files on drives?

By the way, where can I get information about the memory mapping for the Flash?

C/C++ code has no problem accessing files on drive because it uses standar DOS interruptions... but of course it cannot change the files' content. To do so you have to "ask" to the flash controller but it's not simple at all. You have to write byte per byte.

A French guy (Whyp) made a fantastic tutorial about the AFX but it's all in French.

You can download it there:
