Reilly has asked for the wisdom of the Perl Monks concerning the following question:

How to I express HEX values in substitution strings. I want to find a FF 30 39 which is also an 09. The 09 is a tab jump which is not in play here. My file to be converted has FF 30 39 when I do a HEX dump. I need to convert hyphens (-) to FF 30 39. Can someone help?

    Like in any other interpolating string: \xFF\x30\x39 or \x{FF}\x{30}\x{39}

      I don't know an interpolating string from a violin string. I am not a program. I am writing a large file of substitution strings to convert data structures for a typesetting program. I really appreciate your answer because these conversion tables are the only thing close to programming I have ever done. They are working great except for about three HEX values that were showing up and got me in a corner
