**Code Generation test case 11: Function call implementation using array parameters- usage of both static and dynamic

Multiple modules with the driver module with single level of nesting 



**
<<module array_parameter_demo>>
takes input[ B: array[10..14] ofinteger, C:array[low..high] of integer];
returns [sum1:integer, sum2: integer, sum3:integer];
start
	print(B);
	print(C);               

	declare k, i, p, q: integer;
	get_value(p);	
	get_value(q);
	declare A, D: array[10..14] of integer;                          
	declare E: array[p..q] of integer;         

	get_value(A);
	get_value(E);

**Using local variable A - static array**
	print(A);
	sum1:= 0;
	for(k in 10..14)
        start
		print(A[k]);		**requires dynamic bound checking- value of k is available at run time**
		sum1:= sum1+A[k];
		print(sum1);
	end
	print(A);                   **printing A again to verify that the data of its elements in corresponding locations is intact**
	print(sum1);

**using local variable E - dynamic array**
	E[5]:= E[6]+E[7];                **requires dynamic bound checking - ranges of E are available at run time**
	print(E);

**using parameter B - static array**
	sum2:=0;
	D:=B;
	print(D);
	for(i in 10..14)
        start
		print(D[i]);			**requires dynamic bound checking- value of i is available at run time**
		sum2:= sum2+D[i];
		print(sum2);
	end
	print(D);
	print(sum2);

**using parameter C - dynamic array**
	sum3:=0;
	print(C);
	for(j in 1..4)
	start
		get_value(index);
		sum3:= sum3 + C[index];                 **runtime bound checking required**
		print(sum3);
	end
	print(sum3);
end

**formal parameter C of the callee function array_parameter_demo receives the range values from the actual parameter array_B**
