ME in Method
When we declare a variable of any type in public section of a class then we can use it in the implementation. Let us suppose we declare a variable of any type with an initial value in public section. Then we declare the variable again inside a method initiating with a different value. Now if we write the variable inside the method, the system will print the changed value not the previous one. To reflect the previous value of the variable we have to use ME operator.
In the following example we have declared a public variable v_txt and initiate with a value. Then we have declared the same variable again inside the method but instantiated with different value. Inside the method we are writing that variable with ME operator and get the previously initiated value. By declaring directly we are getting the changed value.
