Subject: Re: adding data to a file before it gets regexed
Thanks Chas for the reply
what I'm trying to do is add the file name to the start of the string beign
placed in the array, I havent used hashes so I'm not fiormlar with using
hashes, but I am open to using them.
The reasion I am trying to add the string to the line, is so that I can use
it in a regex afterwards, so it will break out what file was assiated with
the line, as I have a list of files that i am adding together.
I'm using opendir to get a list of files, then opening the files using open,
but I want to add the file to the string.
