Chapter 3 - Modifying the Mail.mms
Map Source File
The ContactToLabel map introduced in Chapter 1 used a single customer record
to generate a single mailing label. In this exercise, you copy the ContactToLabel
map to a new name in the same Mail.mms map source file. You map multiple
records that may contain the optional middle names to multiple labels.
After you complete the exercises in this chapter, the Mail.mms map source file
will contain the original ContactToLabel map and the new ContactToFullLabel
map. The ContactToFullLabel map uses the FullContact.txt as the data source,
and generates the Label.txt output file.
