I seem to remember that on at least on older version of PS, there was a bug that allowed you to do this. I think it was something like if you created a string, then put a character into it with put, it would survive a save/restore pair. I know that Don Lancaster published some thing about it, and even wrote code to use it, but IT IS A BUG AND IS NOT REPEATABLE unless you have the buggy interpreter. i.e. Not wise to write code for others use that depends on it.
