How to loop through stacks with same name?

[Håkan Liljegren]

Thanks for the tip! But unfortunately already tried that! I only try to work with one stack at a time.

If I set a breakpoint and step over the line
delete stack “teststack"

And then try to open a new stack with the same name there is no dialog box
If I run the same code (without any breakpoints). I can wait forever (well kind of) and the stack will still be among the mainStacks. If I run your suggest code with a counter addition:

repeat while "teststack" is among the lines of the mainStacks
      delete stack "teststack"
      add 1 to tCount
end repeat
put tCount

I get an output of 1 but again if I bring up the message box after the code Is executed and do a “put the mainStacks” the stack is back again! If I run a loop over all my 25 stacks (or so) with the same name using the code above it loops through several stacks in quick succession but then I got the dialog again, and again, and again, and again… until I force quitted LiveCode.

Created there stacks teststack1, 2 and 3 in the same folder all with the same name “teststack”. If I then run the following code from another stack in the same folder:

   set the itemDelimiter to slash
   put item 1 to -2 of the filename of this stack into tPath
   repeat with i = 1 to 3 
      open stack tPath & "/teststack" & i & ".livecode"
      repeat while “teststack" is among the lines of the mainStacks
         delete stack "teststack"
      end repeat
   end repeat

Then I get a dialog asking what I want to do with teststack1 before I load teststack2 and teststack2 is still open after the code has run! If I create 6 stacks and run the same code (but from 1 to 6 of course) I get into the unstoppable dialog loop and needs to quit LiveCode! 

I’ve update the bug report https://quality.livecode.com/show_bug.cgi?id=24163 with new example ( https://quality.livecode.com/attachment.cgi?id=11421 ) that causes my LiveCode to get into the endless dialog loop. So, don’t run this if you have unsaved work in another stack!

If it works for you Jacqueline, what platform are you using? Maybe this is a Mac only problem? I’m running MacOS Ventura 13.1 on a MacBook Pro (M1 Max).
