What is the usage of the step function in VB?

In VB, the Step function is typically used in conjunction with a For loop to specify the increment of the loop variable.

The steps for using the Step function are as follows:

For loop variable starting from initial value to end value with increment amount
‘Code to be executed in the loop
Next loop variable

The increment parameter in the Step function specifies the amount by which the variable changes in each iteration. For instance, if the increment is 1, the variable increases by 1 each time; if the increment is -1, the variable decreases by 1 each time.

Here is an example using the Step function:

For every even number from 1 to 10, display a message box with the number.

In the example above, the loop variable i starts at 1, ends at 10, and increases by 2 each time. Therefore, the loop will start at 1 and increase by 2 until reaching or exceeding the final value of 10. During each loop, a message box will appear displaying the current value of the loop variable i (i.e. 1, 3, 5, 7, 9).

The use of the Step function in a For loop allows for controlling the increment of the loop variable as needed, offering more flexibility in managing the number of iterations and range of the loop.
