There may be a situation when you need to execute a block of code several number of times. In general, statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on.
Programming languages provide various control structures that allow more complicated execution paths. A loop statement allows us to execute a statement or group of statements multiple times and following is the general from of a loop statement in VBScript.
VBScript provides the following types of loops to handle looping requirements. Click the following links to check their detail.
| Loop Type | Description |
|---|---|
| for loop | Executes a sequence of statements multiple times and abbreviates the code that manages the loop variable. |
| for ..each loop | It is executed if there is at least one element in group and reiterated for each element in a group. |
| while..wend loop | It tests the condition before executing the loop body. |
| do..while loops | The do..While statements will be executed as long as condition is True.(i.e.,) The Loop should be repeated till the condition is False. |
| do..until loops | The do..Until statements will be executed as long as condition is False.(i.e.,) The Loop should be repeated till the condition is True. |
Loop Control Statements
Loop control statements change execution from its normal sequence. When execution leaves a scope, all the remaining statements in the loop are NOT executed.
VBScript supports the following control statements. Click the following links to check their detail.
| Control Statement | Description |
|---|---|
| Exit For statement | Terminates the For loop statement and transfers execution to the statement immediately following the loop |
| Exit Do statement | Terminates the Do While statement and transfers execution to the statement immediately following the loop |
