This article mainly introduces "the usage of For...Next sentences in VBS". In daily operation, I believe many people have doubts about the usage of For...Next sentences in VBS. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "the usage of For...Next sentences in VBS". Next, please follow the editor to study!

Executes a set of statements repeatedly a specified number of times.

For counter = start To end [Step step]

[statements]

[Exit For]

[statements]

Next

Parameter counter

A numeric variable used as a loop counter. This variable cannot be an array element or an element of a user-defined type.

Start

The initial value of counter.

End

The final value of the counter.

Step

The step size of the counter. If not specified, the default value for step is 1.

Statements

One or more statements between For and Next will be executed a specified number of times.

Description

The step parameter can be positive or negative. The value of the step parameter determines the execution of the loop, as follows:

Value if. Then loop through a positive number or 0counter = end

When the loop starts and all statements in the loop are executed, the step value is added to the counter. At this point, either the statement in the loop executes again (based on the same test as when the loop starts), or exits the loop and continues execution from the statement after the Next statement.

Note that changing the value of counter in the loop will make it more difficult to read and debug the program code.

Exit For can only be used in For Each...Next or For...Next structures, providing another way to exit the loop. You can place any Exit For statement anywhere in the statement. Exit For is often used with conditional judgment statements (such as If...Then) and immediately transfers control to statements after Next.

You can place one For...Next loop in another For...Next loop to form a nested loop. The counter in each loop uses a different variable name. The following structure is correct:

For I = 1 To 10 For J = 1 To 10 For K = 1 To 10. . . Next NextNext at this point, the study of "the use of For...Next sentences in VBS" is over. I hope to be able to solve your doubts.
