Often, it becomes necessary for programmers to want or need to store structured data, such as the attributes of a person, for example. In Pascal, we can declare a record type. This is a user-defined data type to store structured data as follows:
type TPerson = record name: String; age: Integer; gender: TGender; // TGender is assumed here to be an enumerated type that holds the values Male and Female end;
Next, we can use TPerson as a type in our code in the following ways.
var p: TPerson; x: integer; begin p.name := 'Bob'; p.age := 37; p.gender := Male; x := p.age; end;
The 'with' clauseEdit
As you can see in the above example, the calls to our record variable get a little tedious. Fortunately, Pascal offers us the 'with' clause. This will ease the way you use record (and Turbo Pascal-compatible object) variables.
with p do begin name := 'Bob'; age := 37; gender := Male; end;
