A record (analogous to a structure in some languages) represents a heterogeneous
set of elements. Each element is called a field. The declaration of the record type
specifies a name and type for each field. The syntax of a record type declaration is

type recordTypeName = record

fieldList1 : type1;
...
fieldListn : typen;

where 

recordTypeName

is a valid identifier, each 

type

denotes a type, and each

fieldList

is a valid identifier or a comma-delimited list of identifiers. The scope of

a field identifier is limited to the record in which it occurs, so you don’t have to worry
about naming conflicts between field identifiers and other variables.

Note: In mikroPascal PRO for AVR, you cannot use the 

record

construction direct-

ly in variable declarations, i.e. without 

type

.

For example, the following declaration creates a record type called 

TDot

:

TDot = 

x, y : real;

Each 

TDot

contains two fields: x and y coordinates. Memory is allocated when you

declare the record, like this:

var m, n: TDot;

This variable declaration creates two instances of TDot, called 

m

and 

n

.

A field can be of previously defined record type. For example:

// Structure defining a circle:
type

TCircle = 

radius : real;
center : TDot;
