[Gambas-user] Gambas3 byref behavior

[Jussi Lahtinen]

Hi
I could be wrong, but.
I think that byref command should behave like this:

a = 0
TestFunction(a)
Print a

Public Function TestFunction(Byref x as Integer)
 Inc x
End

Result:
1


And if you like to pass byref argument byval instead for some reason,
you should do this:

a = 0
TestFunction(Byval a)
Print a

Public Function TestFunction(Byref x as Integer)
 Inc x
End

Result:
0

There are reasons why one design function to take parameters byref,
and so, it should be default behavior.
Need to pass byref argument byval is rare exception (I think).
Maybe there are some technical restrictions why this is as it is.
And maybe this is not good enough reason to change syntax anymore...
What do you think?
