Description
I can read files, but saving them doesn't work. There is no error message, but the file doesn't seem to go anywhere and can't be read back in.

- Affected version changed from 0.9.5 to 0.9.7
I keep hearing that file saving is supposed to be working, but I've never been able to get any file to save and re-load.
This program still doesn't find the file. Even if you edit out the 'if exists' parts and just try to load it regardless, you get a file not found.

- Status changed from New to In Progress
- Estimated time set to 24:00 h
This is working now, but probably not as you expect. Due to security restrictions, files are being saved to the web browser cache instead of the local application folder. The Exist function is not looking there at the moment, so yes, you will need to bypass that right now.
WARNING 1: Since files are now stored to the web browser cache, if you clear the browser cache, they'll be gone, so be careful of your browser's cache options!
WARNING 2: The browser's application: area is shared by ALL of your AOZ applications, so be aware that if you have the same filenames, your file for one application will be over-written by the other. (If game1 and game2 both have highscore.dat, you'll have problems. For now, just make sure you name them differently: game1_highscore.dat, game2_highscore.dat
We are working on a way to make it so we can save to the local application's folder, but for now, this is the work-around.

I modified your test program, and tested in in the current version: Beta RC2.

- Assignee changed from Francois Lionet to Baptiste Bideaux
- Affected version changed from Beta RC2 to 1.0.0 (B8)
Re-tested in 1.0.0 (B8) June 3.
Still fails.
Here's a simpler example:
Open Out 1,"MyFile.dat" ' Should open "MyFile.dat" on default file system.
Print #1,"test" ' Gets File Not Opened error (ever after Open Out succeeds)
Close 1 ' Close also fails even after Open Out.
Dir ' Should show directory of default file system with "MyFile.dat" in it.
The above fails at Print #1
If that line is commented, then it fails at Close 1
My guess is therefore that probably (although no error was displayed), Open Out probably failed, or failed to do something it needed to to tell the other file commands that the file is open and ready for writing.

This all seems to be working in Beta 10.
I can't change the status to closed while it's "In Progress"

I still find it wont write anything if the file exists or not in Beta 10 same as Brian.

The Reading tho works fine from disk.
Note: I did test mine and pauls code again, (Pauls below) it does seam to
say as mine it reads and writes ok but, writing where ok if its working
then it is working in browser cache/memory ok as paul confirms in vivaldi https://discord.com/channels/653893653940404224/777642924275400715/893549838438924298
but yeah not to real disk at all still at this point.
(Nothing writes from application but as brian points out above still that is wip).
..
#splashScreen:false
print "Current directory:";dir$
Open Out 1,"test.txt"
Input "Please enter your name ";name$
Print #1,name$
Close 1
print "File written, now reading..."
name$="blank"
Open In 1,"test.txt"
Input #1,name$
Print "Hello ";name$
Close 1

Tested writing again, still in Rel 1.0 beta 11 wont write to actual file.
