Sense of VBArray?

Do anybody know, which advantages VBArray have?
http://code.google.com/p/jabacoframework…BA/VBArray.java

Jabaco code like

Jabaco Source

 
1

Dim b() As Double
is compiled to

Jabaco Source

 
1

Dim b As VBA#VBArrayDouble


With Dim it happens everytime. And in functions it can be prevented with the Jabaco key-word ByJava:

Jabaco Source

 
1
2

Public Sub main(ByJava args() As String)
End Sub


But currently I don't see any advatage, to use for example VBArrayDouble over instead of an real array of double.
http://code.google.com/p/jabacoframework…rrayDouble.java

I see only the disadvantage, that it is not possible to use arrays with more then one dimension.

Dim a As Integer  ' int a;
Dim b() As Integer ' VBArrayInteger b;
Dim c(,) As Single ' Don't Compile  :-(

Yes, the same question occurred to me.

It might have been better to go for pure Java arrays.
But I'm not sure regarding the implications in terms of compatibility.

Here is an additional funny thing.
In this case it have more to do with the BASIC syntax:

Dim SomeThing1(5) As Integer
Dim Both(3) As Integer

Public Sub CallIt()
  SomeThing1(0) = 7
  SomeThing1(1) = 6
  SomeThing1(2) = 3
  SomeThing1(3) = 45
  SomeThing1(4) = 34
  Both(0) = 23
  Both(1) = 47
  Both(2) = 63
End Sub

Public Function SomeThing2(a As Integer) As Integer
  Something2=a*2
End Function

Public Function Both(b As Integer) As Integer
  Both = b*b
End Function

Public Sub main(ByJava args() As String)
  CallIt()
  Debug.Print SomeThing1(3)
  Debug.Print SomeThing2(3)
  Debug.Print Both(1)
   MsgBox("only a window, to wait. So you can see the debug window")
End Sub


Can you tell - without running that program - which number Debug.Print Both(1) outputs? :)

Are "[" and "]" already used in BASIC?

Possible Jabaco could use it for Arrays.

So in Java:

Source code

 
1
2
3
4
5
6

int a[] = new int[4];
double b[][] = new int[45][23];

int a(int h) {
return h*7;
}


is in the current Jabaco (and in BASIC):

Jabaco Source

 
1
2
3
4
5

Dim a(4) As Integer
Dim b(45,23) As Double 'Currently not supported in Jabaco

Function a(h As Integer) As Integer
End Function


And it could be in Jabaco:

Jabaco Source

 
1
2
3
4
5

Dim a[4] As Integer
Dim b[45,23] As Double 'Currently not supported in Jabaco

Function a(h As Integer) As Integer
End Function


I think, then there it is more improbable, to misread the code.
