Variable substitution in switch statement not working

Hi Vernon, Thanks for your much informative and elaborate answers. Appreciate it. I earlier tried to put the "\" at end of each case but gave me syntax error. your answer puts \ at the end of each line even inside the case. I am not sure if its feasible for me as I have some 200 lines of code in the switch statement, which includes another switch in one or more cases, and to keep \ at end of each line. I will try this out and see if that removes the syntax errors.
