Every time I run this script with warnings on I get a warning that the variable $location is undeclared once for each line in the @workingdata array and I don't understand why. It appears to use "0" in the pattern match because it never matches any line which it would if it used "".

I have tried taking the my out of the each statement and declaring both $location and $devices as global variables and the script runs with the same warning only once instead of once for each entry in the array and the script hangs eating the same amount of processor and ram but never generates any output to the file. Any help is greatly appreciated.
