Re: REGEX with input file

Any number of things may be wrong with your code. You haven't given us enough information to tell. You don't even say what output you are getting instead of what you want. Here are a few ideas of what could be wrong:

Not really a problem but the conditional is redundant. The s/// will only do its job if the LHS actually matches.
is outputfile really a filehandle opened for output?
Is SETORA really a filehandle opened for intput?
Are you sure you're checking the right file to see your results?
