Swap disks problem

[sovenyimre]

I'd like to ask for a little help:

Files managed by AMOS game can't fit on one disk, so I have to manage them on multiple disks.

-First, when I check with "Exist ("file")" if the disk needed to be replaced, but then... it remembers the current status of the file I am looking for and I allways get "Exist ("file")=-1"even after I am changing the disk with the right file on.
It seems to be memorized and I can't delete it.

-Second version. If I use "Trap Load file: Errtrap = 81" instead of "Exist", the first disk change will work, it finds the file I am looking for, but... from now on, it will also memorized as existing file (and all the files I used before) and treat these files as if they were existing in the current one.
gain, I get "Exist (file) = - 1" for each file, does not matter if I use full path or just a filename.

I assume the existents of the files are stored/buffered somehow, which I should reset, and I cant find any information how to do this!?

If anyone can help me, or tell me where can I find a working example/solution to my problem?

Thank You.

The "file exists bug" is an Amiga Workbench bug and dates back pretty far. I don't think that solution is going to work.

If you want a consistent look and feel with your game and the "please insert disk named ..." requester, you can theme the Amos GUI with a custom resource bank. This will insure that the familiar aqua-scale requester on an orange background is not as ugly and will use a different palette. In fact the entire Amos GUI can be themed using a resource bank.

Sadly.... my quest continues.
Thank You, Samurai!

Aha, thats wb's bug. Some time ago I've encountered the same problem but with Blitz Basic.

The source abowe was the test program I used.
I spent weeks search to find a solution, and when I ask for , the (SIMPLE!) code suddenly works without alteration.

It must be sorcery!

Thank's for everyone

edit:
I know what sorcery caused the problem.
