Problem with For ... to... next

[MrSergey]

Simple code

For $i = 1 to 10

Next

MsgBox(0,"",$i)

Result = 11

Why?

[monoceres]

Simple. The loop executes while $i is less or not equal to 10. Therefor it doesn't quit until $i=11 (however the code inside the loop doesn't get executed when $i=11).

Simple code

Result = 11

Why?

Simple. The loop executes while $i is less or not equal to 10. Therefor it doesn't quit until $i=11 (however the code inside the loop doesn't get executed when $i=11).

Consider the following further examples:

For $i = 1 To 10
    ConsoleWrite("Inside For/Next loop:  $i = " & $i & @LF)
Next
ConsoleWrite("After For/Next loop:  $i = " & $i & @LF & @LF)


$i = 0
Do
    $i += 1
    ConsoleWrite("Inside Do/Until loop:  $i = " & $i & @LF)
Until $i = 10
ConsoleWrite("After Do/Until loop:  $i = " & $i & @LF & @LF)


$i = 0
While 1
    $i += 1
    ConsoleWrite("Inside While/WEnd loop:  $i = " & $i & @LF)
    If $i >= 10 Then ExitLoop
WEnd
ConsoleWrite("After While/WEnd loop:  $i = " & $i & @LF & @LF)

Note you could add "If $i >= 10 Then ExitLoop" to the bottom of the For/Next loop also and get execution on $i = 10, and it will still be 10 after the loop.
