VBScript - Loops
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 for 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.
|for loop||Executes a sequence of statements multiple times and abbreviates the code that manages the loop variable.|
|for ..each loop||This is executed if there is at least one element in group and reiterated for each element in a group.|
|while..wend loop||This 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.
|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|
