A record is a data structure (like an array) which can store values with different data types.
Each item in a record is called an attribute (or field). Each attribute is given an identifier (name) and data type.
Records are fixed in length. Attributes cannot be added or deleted, but they can be changed.
Example 1 shows how to create a record structure.
Example 1
RECORD film
name: STRING
releaseYear: INT
duration: INT
rating: REAL
ENDRECORD
Example 2 shows how to assign values to the record.
Example 2
film.name ← "Avengers: Endgame"
film.releaseYear ← 2019
film.duration ← 182
film.rating ← 8.4
Example 3 shows how to manipulate records.
Example 3
OUTPUT film
>>>
{name: "Avengers: Endgame",
releaseYear: 2019,
duration: 182,
rating: 8.4}
OUTPUT film.rating
>>> 8.4
film.rating ← 8.3
OUTPUT film.rating
>>> 8.3
What would be wrong with writing
film.rating ← "8.5"?
The rating attribute needs to be of the REAL type, but "8.5"
is a string.
