Formatting a disk

[Pengwin]

Just asked this over in the programming forum, but I thought I would ask here as well:

 

I am writing a project in Kyan Pascal, but I need the program to format a disc before storing data. I cannot find a way of doing this directly from pascal, so I was hoping someone out there might have an assembly listing of a format routine I could then embed in the pascal source.

 

I am using an 800XL with a standard 1050 drive. The DOS that I will be using for the app is DOS2.5

 

Anyone?

Hi,

 

you need to send a CIO Command. The command number is depended from the DOS you're using and the Density you're formatting, mostly between 251 and 254. You'll find a list hare --> http://www.strotmann.de/twiki/bin/view/APG/PgmXIOCmd

 

Kyan Pascal should have a CIO or XIO Command to send CIO Commands to a handler. If not, it can be easily don't from embedded assembler.

Hmmmm, Kyan manual makes no mention of any CIO or XIO calls?

Yeah, that's why I was hoping for an assembler routine. I know the basics of 6502, but have never actually coded anything in assembler.

Here are some C/asm sources for doing XIO that I wrote. They are not perfect.

 

xio.zip

 

 

Here is some info from DERE: http://www.atariarchives.org/dere/chapt08.php#H8_6

And from Mapping: http://www.atariarchives.org/mapping/appendix17.php

XIO commands: http://www.telusplanet.net/public/pairman/xiocodes.txt

 

I *think* that a format can be done in C with the following:

 

#define DISK_IOCB 1
//Open
xio(0x3, DISK_IOCB, 4, 0, "D1:", 0)
//Format double density first/ then single density
xio(0xfe, DISK_IOCB, 0, 0, , "D1:", 0);
//Format double density only (DOS 2.5)
xio(0xfd, DISK_IOCB, 34, 0, , "D1:", 0);
//Format single density only (DOS 2.5)
xio(0xfd, DISK_IOCB, 0, 0, , "D1:", 0);

 

I have not tried the above, but this is what I think will work...

Oooh.. Look what I found on cas's site:

Thanks Cybernoid, that and your previous post should give me enough to write a format routine.

[Cybernoid]

No problem. Good luck on your project and please be sure to post your "personal accounts" here..

 

Yes, I really do read Krazy Pengwin's Atari 8-bit Home...

That's good, means I'm not talking to myself when I update the blog or projects

 

Of course I will post the finance package on here. Or rather, I'll put a link to my site when it's ready for distribution. Not sure when that will be though, I seem to be working in stops and starts at the moment.

Thanks for the link to the CIO libraries Cybernoid.

 

I have created a format routine based on the open function, and it works.

 

I am also in the process of creating a Get_Dir function and a File_Exists function. With these libraries, my program should be a lot more professional and robust.

 

And thanks to Carsten for writing them
