Re^16: Help needed with regard to arrays

OK , I checked out @lines. It appears that the code is "working as written". The "storeplaceholder" gets overwritten by the value of $item but then that $line is assigned to the next thread. The regular expression obviously fails since there is no "storeplaceholder" to replace. Is there a better way to do this? I have tried share(@lines) and lock() with no luck....but I dont think that is the issue here...

Yes, you found the problem. A simple approach could be to use a copy of `@lines` to modify and then execute. That way you would still have the original `@lines` around for the next round. Why do you think that `share()` or `lock()` come into play? Is the problem related to threads? Did you check that? You can easily switch your program into single-threaded mode. Does the error persist? Note that these are all rhetorical questions for me - they are intended to guide you in the process of debugging and eliminating all other possible causes.
