Get a Mail-Merge Replacement String by Pattern

Demonstrates the Chilkat Email.GetReplaceString2 method, which returns the replacement string for a previously-defined pattern/replacement pair, looked up by the pattern itself (a mail-merge feature). This example defines two pairs and looks up the replacement for one pattern by name.

Background: Where GetReplaceString fetches a replacement by its numeric position, GetReplaceString2 fetches it by the pattern — convenient when you already know the token (say FIRST_NAME) and just want its configured substitution without scanning the whole list.
