For what its worth, I have coded a routine called Expand. It is used thus
...

   result = Expand("Prenom {fn}, Nom {ln}", 
			"fn", firstname, "ln", name);
   result = Expand("Surname {ln}, First name {fn}", 
			"fn", firstname, "ln", name);

Where tokens, such as {fn} and {ln} in this example, are used to locate
keys with the same value in the argument list. The argument to the right of
a key is it's associated value. The values are used to replace their
respective embedded tokens in the format string. If the arguments do not
match any token in the format string, the token is just removed from the
output.
