How to store some data in my stack

[吉野 孝]

Hi, Klaus

Thank you for your quick reply!

I changed my script, but it does not work on an android.
(It does work on my mac.)


The following are the test script.
(URL is very easy! thanks)

- Write button
on mouseUp
   put fld "Data" into URL("file:" & specialFolderPath(“documents”) & "/" & “testFile.txt”)
   put the result into fld "msg"
end mouseUp


- Read button
on mouseUp
   put URL("file:" & specialFolderPath(“documents”) & "/" & “testFile.txt”) into fld "Data"
   put the result into fld "msg"
end mouseUp

# "/" -> ":"(mac) 
	
On my mac, those scripts work well.

But, on my android, "can't open file" is shown in field "msg"
