Android Question Sub Foo (Arg as String) as String

[MrBcx]

I understand that specifying a return type at the end of a SUB declaration makes it a FUNCTION.

Can someone please explain to me how to invoke a user defined string function like this?



Sub Foo (Arg as String) as String
Return Arg
End Sub

Like this:

MsgBox(Foo("Say hello back to me"), "")

Or

Msg = Foo("Hi there")

MsgBox(Msg, "")

Thank you NJDude ... that's what I thought.

I'm trying to use a user-defined string function (SUB), in a listview event, to modify a global string but the global string never receives the expected value - instead it get changed to an empty string. Baffling ...

In that particular case you might not need to use RETURN, just change the value of that variable on the SUB.
