2	+
3	+	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.
4	+
5	+	To declare a record, you'd use:
6	+
7	+	``` pascal
8	+	TYPE
9	+	TypeName = record
10	+	identifierlist1 : datatype1;
11	+	...
12	+	identifierlistn : datatypen;
13	+	end;
14	+	```
15	+
16	+	For example:
17	+
18	+	``` pascal
19	+	type
20	+	InfoType = record
21	+	Name : string;
22	+	Age : integer;
23	+	City, State : String;
24	+	Zip : integer;
25	+	end;
26	+	```
27	+
28	+	Each of the identifiers `Name, Age, City, State`, and `Zip` are referred to as fields. You access a field within a variable by:
29	+
30	+	``` pascal
31	+	VariableIdentifier.FieldIdentifier
32	+	```
33	+
34	+	A period separates the variable and the field name.
35	+
36	+	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:
37	+
38	+	``` pascal
39	+	WITH RecordVariable DO
40	+	BEGIN
41	+	...
42	+	END;
43	+	```
44	+
45	+	Example:
46	+
47	+	``` pascal
48	+	with Info do
49	+	begin
50	+	Age := 18;
51	+	ZIP := 90210;
52	+	end;
53	+	```
