Question about For

[FuryCell]

This question has bugged me for quite some time now.

If i use code like this will the script keep recalculating the line count or just calculate it once?

#Include <Array.au3>
#Include <File.au3>
Dim $Array[1]
$File = FileOpen("C:\Test.txt", 0)
For $X = 1 To _FileCountLines($File, "")
    _ArrayAdd($Array, FileReadLine($File))
Next
FileClose($File)
_ArrayToClip($Array, 1)

(Note:This was just an example to demonstate my point and serves no real purpose. )

seems only first time... as it should be... methinks

but, here is one that haunts me...

For $n = 1 to 10
   MsgBox(4096,"",$n)
   $n = $n + 1
Next

It makes sense, I guess... I first thought AutoIt would give an error saying that $n was readonly or something...

Yes. It appears this holds true for functions too , at least user defined ones. I just made a small script to test it.

Global $TestFuncTimes
For $X=1 to _TestFunc()
    ToolTip($X)
Next


Func _TestFunc()
    $TestFuncTimes=$TestFuncTimes+1
    MsgBox(32,"TestFunc.","Test Func has been executed " & $TestFuncTimes & " times.")
    Return 10
EndFunc

anyway thanks for the feedback Larry.
