>What is a good way to create form letters in a VFP application and insert data from a table into each letter like a mail merge file?

Another way is (if your client has Office Professional) to simply create a table, and fire up a pre-written word document which references the fields in the table. (See Mail-Merge/Set datasource options in Word) This makes it very easy for the user(s) to amend the form letter, and is so simple to program. It then allows all the powerful native features of Word merge facilities.

BTW, I'm not sure, but you may need to create the table as a Foxpro 2.6 version, but that's fairly easy too (COPY TO...)
