[SOLVED] AU3Check WARNING: $oOL_Recurrence: declared, but not used in func

[water 1,935]

This little test script always gives

Test.au3(4,56) : WARNING: $oOL_Recurrence: declared, but not used in func.
    Local $oOL_Recurrence = $oOL_Item.GetRecurrencePattern
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^
Test.au3 - 0 error(s), 1 warning(s)
->11:54:52 AU3Check ended.rc:1

although the variable is used in the function.

#AutoIt3Wrapper_AU3Check_Parameters= -d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
#AutoIt3Wrapper_AU3Check_Stop_OnWarning=Y
Func _test($oOL_Item)
    Local $oOL_Recurrence = $oOL_Item.GetRecurrencePattern
    $oOL_Recurrence.RecurrenceType = 2
EndFunc

Is there any way to suppress the warning?

Like this >>

#AutoIt3Wrapper_AU3Check_Parameters= -d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
#AutoIt3Wrapper_AU3Check_Stop_OnWarning=Y
Func _test($oOL_Item)
    Local $oOL_Recurrence = $oOL_Item.GetRecurrencePattern
    $oOL_Recurrence.RecurrenceType = 2
    ConsoleWrite($oOL_Recurrence & @CRLF)
EndFunc

Correct. That suppresses the warning.

I found that

$oOL_Recurrence = $oOL_Recurrence

does the same.

But as the lines will be part of an UDF (guess which ) I want it to be as "elegant" as possible.

Ah OK, sorry I wasn't much use first of all, but your little tweak works.

[Jos 1,507]

The reason for the warning is that the Variable isn't used in any function or on the right side of an equation. That is why your workaround fixed the warning.

Use the #ForceRef directive to "tell" au3check to skip the warning for the variable.

I tried #forceref and for some reason it didn't work, because I was going to suggest this

Update: I did this and it failed >>

#AutoIt3Wrapper_AU3Check_Parameters= -d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
Func _test($oOL_Item)
    #forceref $oOL_Recurrence
    $oOL_Recurrence = $oOL_Item.GetRecurrencePattern
    $oOL_Recurrence.RecurrenceType = 2
EndFunc

but then I realised it should have been this >>

#AutoIt3Wrapper_AU3Check_Parameters= -d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
Func _test($oOL_Item)
    Local $oOL_Recurrence = $oOL_Item.GetRecurrencePattern
    #forceref $oOL_Recurrence
    $oOL_Recurrence.RecurrenceType = 2
EndFunc

Sorry
