Durden,

The only change that I need is that I do not want the 'E' to be written over the current character, but instead it needs to be inserted.

Thanks again.

---------- Post updated at 12:58 PM ---------- Previous update was at 12:49 PM ----------

Just figure out that I need to change the "1" to "0" in Durden's example. Thanks a million to both of you.

perl -lne 'substr($_,777,0) = "E" if length != 874; print' $filename > dc_3.txt
