Record

Record is a structured data type. It contains some elements or fields, and each field can have a different data type. See the picture below.

How to declare a record ?

You have to declare a record after type clause.


type

    RecordTypeName = record

       Field_1 : DataType;

       .

       .

       Field_n : DataType;

    End;

var

   RecordName : RecordTypeName;

For example, we declare a record named ItemStock that has three fields ( Item, Quantity and Price ).


type

   TRecordItem = record

     Item : string;

     Quantity : integer;

     Price : currency;

   end;

var

   ItemStock : TRecordItem;


First, define a TRecordItem then use it to declare a variable named ItemStock. So the ItemStock variable has three fields : Item, Quantity and Price.
