Get a Mail-Merge Replacement String by Index

Demonstrates the Chilkat Email.GetReplaceString method, which returns the replacement string for the Nth previously-defined pattern/replacement pair (a mail-merge feature). The index is zero-based and corresponds to the same index used by GetReplacePattern. This example defines two pairs and prints each pattern with its replacement.

Background: Pairing GetReplacePattern (the token to find) with GetReplaceString (the text to substitute) at the same index lets you walk the full mail-merge table. Retrieving a replacement by its position is handy when enumerating all substitutions; to look one up by its pattern instead, use GetReplaceString2.
