fixed length field

    0.43 sec.

A constant field size; for example, a 25-byte name field takes up 25 bytes in each record. It is easier to program, but wastes disk space and restricts file design. Description and comment fields are always a dilemma. Short fields allow only abbreviated remarks, while long fields waste space if lengthy comments are not required in every record. Contrast with variable length field.
