You're trying too hard. You don't need pack, unpack or "hex editing".

Update: As pointed out by dave_the_m below, I mixed up my options: Switched -n for -p

This should work if you're on Windows:

perl -ple"binmode*ARGV if $.==1; s[P200000976][Test123456]g;" <infile 
+>outfile

[download]

Or this if you're on *nix:

perl -ple's[P200000976][Test123456]g;' <infile >outfile

[download]

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
