Step 6: Now click on ‘F7’ to exit from the subroutine. You will see the below shown screen.

Step 7: At this point, double click on ‘code’ and you will see it below with its current value which is ‘SHOW’.

Step 8: Now I change the value ‘SHOW’ to ‘EDIT’ and save the changes by clicking on the change button shown below.
