Var is a keyword used to mark the section where variables and their data types are declared. When used for a parameter of a procedure or function then var indicates the use of a variable parameter.

Variables are typically declared at the beginning of a program, procedure, function or unit.

var
  age: integer;

If you are planning to use various variables of the same type, they can be grouped so they share the same type definition. The variables must be separated by a comma.

var
  FirstName, LastName, address: string;
