sed command

Hi all!
Need a little help on a sed command that I've used in the past, but I'd like to change it up a bit. Here is my script

Code:
SearchVal = "RED"
ReplaceVal = "BLUE"
wrkFile = /u/tmp/file1
srcFile = /usr/temp/prodfile

sed "/${SearchVal}/s/^\(.\{101\}\).\{7\}/\1${ReplaceVal}/" $wrkFile > $srcFile

What I'm looking to do is rather than using variables, I'd like to just perform the sed command without variables. Such as....
Code:
sed "/${RED}/s/^\(.\{101\}\).\{7\}/\1${BLUE}/" /u/tmp/file1 > /usr/temp/prodfile

I've tried without the "$'s" but that didn't work? am I missing something??

Thanks!

NAME
diff3 - 3-way differential file comparison SYNOPSIS
diff3 [ -ex3 ] file1 file2 file3 DESCRIPTION
Diff3 compares three versions of a file, and publishes disagreeing ranges of text flagged with these codes: ==== all three files differ ====1 file1 is different ====2 file2 is different ====3 file3 is different The type of change suffered in converting a given range of a given file to some other is indicated in one of these ways: f : n1 a Text is to be appended after line number n1 in file f, where f = 1, 2, or 3. f : n1 , n2 c Text is to be changed in the range line n1 to line n2. If n1 = n2, the range may be abbreviated to n1. The original contents of the range follows immediately after a c indication. When the contents of two files are identical, the contents of the lower-numbered file is suppressed. Under the -e option, diff3 publishes a script for the editor ed that will incorporate into file1 all changes between file2 and file3, i.e. the changes that normally would be flagged ==== and ====3. Option -x (-3) produces a script to incorporate only changes flagged ==== (====3). The following command will apply the resulting script to `file1'. (cat script; echo '1,$p') | ed - file1 FILES
/tmp/d3????? /usr/lib/diff3 SEE ALSO
diff(1) BUGS
Text lines that consist of a single `.' will defeat -e. Files longer than 64K bytes won't work. DIFF3(1)
