Cleansing of corrupted stack

[mvillion]

HI

I have been working on a stack in version 6.7 and suddenly it got corrupted. I cannot explain it or how.
I have managed to open it in version 7 but it will not open in 6.7

Is there a clean up mechanism that can be performed to strip it down and rebuild it as I no longer trust the base stack.
Something like an XML export and reimport to rebuild the binary or some other trick.

Would saving it as an earlier version (5.5 format) work?

This is not the first time I have had a stack go bad on me and there is no warning. I save regularly but unless I am closing down and reopening the stack there is no indication it has gone corrupt.

I am thinking I am going to need to set a timer for 30 minutes and save and reopen just to protect myself.

On another matter. The other day a script stopped working. It was reporting something was wrong but the text was correct. What it turned out to be was a hidden character got typed. I guess I must have mistyped it. I was surprised that there is no validation scripts to look for this to ensure that only standard characters are within the script window.

Where I am at is I think I am going to have to create a new stack and cut paste items in and HOPE that there is some kind of validation mechanism to ensure that I have a stable stack again.

Version 7 uses a different file format. Just use Save As from within 7 to save it to am older format and you should be fine.

Text validation is entirely up to you. This is extra work, but a good thing. There is no single "right" set of characters for every user. You can always do this once, and save the gadget that works for you in future projects.

What's interesting with "saving in older format" is that one can make this choice permanent (saved with stack) in <LC Preferences / Files & Memory>. This avoids a 'stack corruption' (but also new features) when working with LC 7 on a pre-LC7-stack.

Available (at least) in LC 6.6.5 and later

Going forward they've made this even easier: While it's not possible for an older version of nearly any app to be able to understand formats created after it was written, there are some elements in the LC file format that make it possible for an older engine to at least guess that the file may have been made with a newer version, and to suggest trying that when opening a newer file in an older version.

Accordingly, this enhanement was introduced in v7.0, and has been backported to v6.7.1 which is now in testing as "RC1".
