The other thing, I see now that I was testing with fixed format files format and not more general files as you show. Certainly it won't work
only with my simple test filesSmilie. I'll try to adapt it in some other way if I can in order to work with other filesSmilie

Your first code works fine with my test files, but the 2nd code prints the same file2, as below:

Code:
$ cat file1
$myName$|xxx
$yourName1$|xxy
$hisName$|zzz

$ cat file2
Your name is $yourName$
My name is $myName$
His name is $hisName$

$ awk -F\| 'NR==FNR{rep[$1]=$2; next;}
{ for(r in rep) gsub(r, rep[r],$0);
  print $0 }' file1 file2
Your name is $yourName$
My name is $myName$
His name is $hisName$

Regards

diff3(1)						      General Commands Manual							  diff3(1)

Name
       diff3 - 3-way differential file comparison

Syntax
       diff3 [-ex3] file1 file2 file3

Description
       The command compares three versions of a file, and publishes the ranges of text that disagree, flagged with the following codes:

	  ====	      all three files differ

	  ====1       file1 is different

	  ====2       file2 is different

	  ====3       file3 is different

       The type of change needed to convert 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.

Options
       -3   Produces an editor script containing the changes between file1 and file2 that are to be incorporated into file3.

       -e	   Produces an editor script containing the changes between file2 and file3 that are to be incorporated into file1.

       -x	   Produces an editor script containing the changes among all three files.

Examples
       Under the -e option, publishes a script for the editor that incorporates into file1 all changes between file2 and  file3  -  that  is,  the
       changes	that would normally be flagged ==== and ====3.	Option -x (-3) produces a script to incorporate only changes flagged ==== (====3).
       The following command applies the resulting script to `file1':
       (cat script; echo '1,$p') | ed - file1

Restrictions
       Text lines that consist of a single `.'	defeat -e.

Files
       /tmp/d3?????
       /usr/lib/diff3
