Swap disks problem
 

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.
I assumed the same and would like to know too if theres some solution.

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

It must be sorcery!:guru

Thank's for everyone :great

edit:
I know what sorcery caused the problem.
