Cautionary tale of open, append, close

[doppler]

It's exactly what I am doing.  Log file "common" to respective machine logs "specific".  Thinking about it, I am just using a for/next loop to search open files in use.  But using the for value as the file open number.  I am going to change the open handle to the safer FREEFILE function.  All output handles are in the arrray I am searching for filenames.  So the value of the handle does not have to be known.  Only stored for look up.
