Field (computer science)

Identifying related data as a single group is central to the construction of understandable computer programs.

The following Pascal record definition has three field identifiers: firstName, lastName, and age.

Once the memory of the record is allocated, a field can be accessed like a variable by using the dot notation.

To accomplish the arbitrary access, the operating system provides a method to quickly seek around the file.

File fields are the main storage structure in the Indexed Sequential Access Method (ISAM).
