About choosing a field type
When you define a field, you select a field type based on the kind of information the field will contain. The
field type determines what kind of data can be entered and what kinds of operations FileMaker
Pro can
perform with the data. FileMaker
Pro uses the field type to interpret the data for tasks like sorting records
and performing calculations.
