Maps and Map Source Files
A map defines how to generate a data object of a certain type or multiple
independent data objects, each of a certain type. A map contains input and output
cards that transform data content from source formats to destination formats
according to rules contained in the map.
A map source file is used to store maps that are related to one another. A map
source file is a file you create and save using the commands on the File menu in
the Map Designer. A map source file has the file name extension .mms. A map
source file maintains maps in source format. Map source files contain maps and
functional maps.
