I am calling prog B from prog A. In A i have intialized the variable num1 to 10 but in prog B i was change this num1 to 20. AT the time of return the program i want to num1 as 10. That means the value at prog A.
Is it possible? If so can any body expalin it with example.
before call in prog A num1 is 10
and in called prog B num1 is 20. When i return the prog B to prog A i want the intial value of num1 which has intialed before the call B from A as 10.
Is it possible or not?
