Fields
Fields are a breakdown of data in a single register. Most programs expect to see
related values on the same line. Each line is referred to as a
record,
and each
item on the line is called a
field.
The fields are either set to a fixed length (so that they appear in columns in the
data file), or they are allowed a variable length with a separator (such as a
comma) separating them. You can also use a template to break apart data
stored in a register into separate fields.
