Array.Sort() is a *method* :-)
It rearranges the elements of the object it is applied to and returns that
object afterwards. That is, you will always have
aArray == aArray.Sort()
where == should be read as "are the same object", despite == not being a
Gambas operator (I use it here to distinguish between the same-object
relation and an assignment).
So, the actual work is done on the object you use to the method on and the
return value is just for brevity in certain applications like
Print aArray.Sort().Join(",")
' or
For Each sElt In aArray.Sort()
Print sElt
Next
' or
With EliminateSuccessiveDuplicates(aArray.Sort())
Print .Count;; "unique elements:"
For iInd = 0 To .Max
Print .[iInd]
Next
End With
If you want truly function-like semantics, then you can use the idiom
aArray.Copy().Sort()

It's a compiler shortcut that comes from Visual Basic. I said "statement", not "procedure", because the interpreter makes no difference between a procedure (that returns nothing) and a function (that returns something) in the sense that it discovers that behaviour at runtime during the execution ; contrary to you, that knows that in advance.

Re: [Gambas-user] Array.Sort
"The empty set of parentheses is REQUIRED when sort is used as a function to return an array without the optional mode parameter" I don't know. Wouldn't it be more accurate to say that the parentheses are required to be able to use the function call as the object which it returns; as opposed to the syntax, without the parentheses, referring to the function itself?

The parentheses "()" may be left out if the method is used purely to manipulate the internal state of the object (whether or not that method may return a value). Examples Consider a hypothetical class method "Negate" that inverts the value of some attribute of the object and returns that value. Thus the "()" is required for: SomeLocalVar = MyObject.Negate() Print MyObject.Negate() but MyObject.Negate is perfectly legal. In this case the value is inverted but the result is "thrown away" by the interpreter.

Re: [Gambas-user] Issue 589 in gambas: Interpreter Crash Gambas3 - Calling a library function - BananaPi
Comment #5 on issue 589 by scrcarl...@gmail.com: Interpreter Crash Gambas3 - Calling a library function - BananaPi https://code.google.com/p/gambas/issues/detail?id=589 Dear Benoit, to be honest, I have reached a point where I have to make a decision if to continue with Gambas 3 or not. The problem is exactly this function PMD_Find_Interface(). Its function prototype is PMD_Find_Interface (HIDInterface** hid, int interface, int productID). HIDInterface is a structure with a lenght of 52 bytes. The problen is how to code it in Gambas: 1.) HIDInterface* hid(7); how to transscribe this in Gambas 2.) interface = PMD_Find_Inteface ( &hid[i], i, USB1608FS_PID); how to setup this call So I have to establish a construct of 7 memory blocks which are accessed by pointers each. I am not interested in the content of these blocks, I only have to transfer it from one function to an other by hid[]. If this can not be done by Gambas 3 I have to stop all activities and have to look for other IDEs. In the past I have developped many testprograms under VB6, therefore I came to Gambas3. In my test setups I have to adress many test equipment via USB in many cases on low level. -- You received this message because this project is configured to send all issue notifications to this address.
