We declared a variable i as an integer. We used error handling and specifies that if an error occurs, the macro should jump to the ErrorHandler label. We run a For Loop for the range of i from -1 to 1. For each iteration of the loop, we calculated x as 10/i which becomes undefi...
This chapter teaches you how to declare, initialize and display a variable in Excel VBA. Letting Excel VBA know you are using a variable is called declaring a variable. Initializing simply means assigning a beginning (initial) value to a variable.
