5E - Records (author: Tao Yue, state: unchanged)
A record allows you to keep related data items in one structure. If you want information about a person, you may want to know name, age, city, state, and zip.
To declare a record, you'd use: <delphi> TYPE
TypeName = record identifierlist1 : datatype1; ... identifierlistn : datatypen; end;
</delphi>
For example: <delphi> type
InfoType = record Name : string; Age : integer; City, State : String; Zip : integer; end;
</delphi>
Each of the identifiers Name, Age, City, State, and Zip are referred to as fields. You access a field within a variable by: <delphi>
VariableIdentifier.FieldIdentifier
</delphi>
A period separates the variable and the field name.
There's a very useful statement for dealing with records. If you are going to be using one record variable for a long time and don't feel like typing the variable name over and over, you can strip off the variable name and use only field identifiers. You do this by: <delphi> WITH RecordVariable DO BEGIN
...
END; </delphi>
Example: <delphi> with Info do begin
Age := 18; ZIP := 90210;
end; </delphi>
