If a value is not assigned to a variable when it is
defined, the system initializes it with zero.
Variables must be defined at the beginning of the
program before use. The definition must be made in
a separate block; only one variable type can be
defined per block.

1.2 Variable definition
A variable of type INTEGER is created with
the name NUMBER.
The system initializes the variable with zero.
A variable of type INTEGER is created
with the name NUMBER. The variable is
initialized with the value 7.
A variable of type REAL is created with the
name DEPTH.
The system initializes the variable with
zero (0.0).
A variable of type REAL is created with the
name DEPTH. The initial value is 6.25.
It is also possible to define several variables
in a single line.
