Returns of 2 variables in one func

[ddarek]

Hello

I am struggling with such a thing

Func FindEmptyField() ;
        For $i = 1 To $iLast
                For $j = 0 To $jLast
                        ;ConsoleWrite("Checking: " & $i & ", " & $j & @CRLF)
                        $FieldInfo = GetField($i, $j)
                        If GetField($i, $j) = 0 Then
                                ConsoleWrite($i & ", " & $j & "  <-Can move! " & @CRLF)
                                ExitLoop
                        EndIf
                Next
        Next
EndFunc

I would like that this function returns first first $i and $j which i can use

I thought about Array but I think it is could be too heavy, maybe with setextended will be nicer ?

Any help ?

Look at SetError()

Like this ?

Func FindEmptyField() ;
        For $i = 1 To $iLast
                For $j = 0 To $jLast
                        ;ConsoleWrite("Checking: " & $i & ", " & $j & @CRLF)
                        $FieldInfo = GetField($i, $j)
                        If GetField($i, $j) = 0 Then
                                SetError($i,$j)
                                ConsoleWrite($i & ", " & $j & "  <-Can move! " & @CRLF)
                                ExitLoop
                        EndIf
                Next
        Next

EndFunc

SetError is to set error values. If you need extended return values, use SetExtended, just as you said.

In your case, an array as return value or ByRef-params should be the best choice. If you don't want an array, use ByRef

Example of returning 2 values with SetExtended

$_Result = _Function ( )
$_extended = @extended
ConsoleWrite ( "$_Result : " & $_Result & ' $_extended : ' & $_extended & @Crlf )

Func _Function ( )
    Local $_Var1 = 100
    Local $_Var2 = 10
    Return SetExtended ( $_Var1, $_Var2 )
EndFunc

@ProgAndy: SetError , ye was absent minded just SetError(1) is enough

@wakillon thnx , but i needed it separately,

so $i I return normal way and $j as SetExtended($j) <- this way it works also

big thnx

Yes, this is identical, values are just crossed.

$_Result = _Function1 ( )
$_extended = @extended
ConsoleWrite ( "$_Result : " & $_Result & ' $_extended : ' & $_extended & @Crlf )

$_Result = _Function2 ( )
$_extended = @extended
ConsoleWrite ( "$_Result : " & $_Result & ' $_extended : ' & $_extended & @Crlf )

Func _Function1 ( )
    Local $_Var1 = 100
    Local $_Var2 = 10
    Return SetExtended ( $_Var1, $_Var2 )
EndFunc

Func _Function2 ( )
    Local $_I = 100
    Local $_J = 10
    SetExtended ( $_J )
    Return $_I
EndFunc
