> ### Variables and constants

> Variables and constants are declared after all parameters but before BEGINMODULE. A variable declaration reminds of a value_parameter_declaration without default_value or prompt_string.
> INT i,j; ! Two INT variables
> FLOAT size; ! A FLOAT variable
> FILE input_data,output_data; ! More than one variable separeted by commas
> Variables may be indexed.
> INT list(100); ! Array of 100 integers
> FLOAT matrix(20,50) ! A 2-dimensional matrix 20 by 50
> FLOAT k(10,5,20,6) ! A 4-dimensional matrix
> and indexed variables may be declared with lower and upper limit...
> INT list(20:50); ! An array of 31 integers
> FLOAT matrix(0:3,0:3) ! A 4 by 4 matrix
> STRING names(0:9)*20; ! An array of 10 names
> If no lower limit is specified MBS uses a lower limit of 1 as default.
> A constant is like a variable but may not be indexed and may not have its value changed. Instead its value is defined once and for all in its declaration...
> CONSTANT FLOAT max_diameter=20.0;
> CONSTANT STRING error_message="Diameter is too large !";
> The FILE type may not be used as a constant.
> Here is a module with some variables and constants:
> !*********************************
> !*
> MODULE init_array();
> !*
> !*********************************
> !*
> INT i;
> FLOAT k(100);
> CONSTANT INT min=1,max=100;
> BEGINMODULE
> for i:=min to max do
> k(i):=0.0;
> endfor;
> ENDMODULE
> !*
> !*********************************
