File order on disk
Hiya!
So, I got an app that removes and creates a file to disk (using kernal, $ffd8).
But where on the disk this file is listed afterwards seems totally random. Is it just me or is it like that?
In vice is seems to keep the position where it was. In ccs it jumps up and down. And the times I've tried it on real hw (/w 1541) it appears at the top.
The problem is that I want the main-app to appear at the top so a load"*",8,1 always loads it, and never this created file.
Any docs anywhere on this?
Thanks!

You can pre-create an entry at the top to delete and rewrite.
Otherwise you'll need to manipulate the directory track directly.

yes, that's what I've ment when talking about directory-entries...ofcoz it has a directory, but not subdirectories! |

A bit off topic but you can use Make Dir to create directories on disk (1541):

K, fiddled some.
As you say, the first free directory-entry is used.
My 3rd file gets removed and then reinserted again, just as I want it to.
BUT when doing a load"*",8,1, the first file isn't loaded. This 3rd file is loaded instead...
Got a MMC Replay inserted. Could that do that kind of thing?

* loads the last accessed file. Only on a fresh boot it loads the first one. |

load":*",8,1 and you're sure. |

I urge you to copy all revelant files to a clean disk before releasing, otherwise you'll have superfluous garbage on the disk. Similar for your binaries, we have seen releases with chunks of source code and other remnants often enough. |

Thank you Steppe. The gamestate file was the last accessed one after my resets, no wonder it loaded it.
And thank you iAN, didn't know that either.
So all, in all, I never had a problem...just user error on my side and some strange behaviour in ccs64.
I just need to rtfm a bit closer in the future.
Thanks all!
ps. so, with this bug out of the window, it's time for you to preorder ;)
