Do And For Statement


A For...Next loop condition can be terminated by an Exit For statement. Consider the following statement block.
Dim x As Integer
For x = 1 To 10
Print x
If x = 5 Then
Print "The program exited at x=5"
End If
Next

The preceding code increments the value of x by 1 until it reaches the condition x = 5. The Exit For statement is executed and it terminates the For...Next loop. The Following statement block containing Do...While loop is terminated using Exit Do statement.
Dim x As Integer
Do While x < 10
Print x
x = x + 1
If x = 5 Then
Print "The program is exited at x=5"
Exit Do
End If
Loop
