Write a syntax for while loop in vbscript

In the first case, the programmer must explicitly write types at certain textual positions for example, at variable declarations. You can place any number of Exit While statements anywhere in the While loop.

You will use Do-While, Do-Until and While-Wend loops when you do not know in advance how many times the block is to be executed. If you change the value of counter while inside a loop, your code might be more difficult to read and debug.

You can nest While loops by placing one loop within another. Transfers control out of the While block. When you need to check for many different cases on one variable you could create a large number of ElseIf statements, but this is actually very inefficient.

In contrast to the for loop, the condition can only contain a boolean expression. A description of the behavior of a translator for the language e.

Among other things, this may permit a single variable to refer to values of different types at different points in the program execution. This parameter determines loop processing according to the following table: Starts the definition of the Do loop.

You typically use Exit While after some condition is evaluated for example, in an If For example, the semantics may define the strategy by which expressions are evaluated to values, or the manner in which control structures conditionally execute statements.

Case Statements - The case statements contain the values we are checking for. Typed versus untyped languages[ edit ] A language is typed if the specification of every operation defines types of data to which the operation is applicable, with the implication that it is not applicable to other types.

Transfers control to the next iteration of the While block. Exit While immediately transfers control to the statement that follows the End While statement.

In contrast, an untyped language, such as most assembly languagesallows any operation to be performed on any data, which are generally considered to be sequences of bits of various lengths.

As you might expect, the Find object is used for finding text in a Word document. Java is a high-level programming language originally developed by Sun Microsystems in This lesson will take it a step further by teaching you how to implement the Select Case statement in VBScript.

Here the condition is checked only after executing the loop once. Thus, the loop condition is usually enclosed in parentheses and the loop body in braces.

An erroneous value or a termination request might create this condition. Dijkstra took the position that the use of a formal language is essential to prevent the introduction of meaningless constructs, and dismissed natural language programming as "foolish".

If condition is still True, the process is repeated. The Continue While statement immediately transfers control to the next iteration of the loop. WriteLine "File Not Found: It also enables you to test condition at either the start or the end of the loop.

You can nest While loops by placing one loop within another. The initial value of counter. For more information, see Continue Statement. The final value of counter. However, if you just have to check a certain condition, you can make use of a while loop.

For example, you want to output the message "Welcome" while the value of the variable x is less than 5. Remarks Use a While Before the statement block runs, Visual Basic compares counter to end.

VBScript Loops - Do While, Do Until, While, For Each

One or more statements that are repeated while, or until, condition is True. This includes values of other data types, such as numeric types, that have been converted to Boolean. Transfers control to the next iteration of the Do loop. The keyword While will continue the loop as long as condition is True.

The keyword Until will continue the loop as long as condition is False. If no condition is specified, the loop will repeat indefinitely or until an Exit Do is encountered. Incredibly old question, but bearing in mind that the OP said he does not want to use Do While and that none of the other solutions really work Here's something that does exactly the same as a Exit Loop.

This never runs anything if the status is already at "Fail". The While Loop. The while loop loops through a block of code as long as a specified condition is true.


VBScript Do..While statement

while (condition) { code block to be executed} Example. In the following example, the code in the loop will run, over and over again, as long as a variable (i) is less than Using Do While or Do Until allows you to stop execution of the loop using Exit Do instead of using trickery with your loop condition to maintain the While Wend syntax.

I would recommend using that instead. A while loop can be simulated in schmidt-grafikdesign.com with::still_more_files if %countfiles% leq 21 (rem change countfile here goto:still_more_files) For example, the following script.
