When multiple variables are DECLAREd in a single statement, parentheses must be used around the variable list to ensure the variable
attributes in the statement are applied to all the variables in the declaration. Without parentheses, the attributes are applied only to the last
variable in the list.
Noncompliant code example
DECLARE X,Y FIXED BIN(15);
Compliant solution
DECLARE (X,Y) FIXED BIN(15);
