Android Question Warning #3[Solved]

Roger Daley · Dec 26, 2016

Hi All

Exposing myself to appear really dumb but what does this really mean?

"Return type (in Sub signature) should be set explicitly."

Yes I understand the words.
Yes, I know I can ignore it but I would prefer use 'Return' correctly.
Perhaps a correct and an incorrect example would help.

Regards Roger

Incorrect:

B4X:

Sub Sum(x As Int, Y As Int)
 Return x + y 'the value will be converted to string as the return type is not explicitly set.
End Sub

Correct:

B4X:

Sub Multiply(x As Int, Y As Int) As Int
 Return X * Y
End Sub
