Hi Laszlo,

Variable scope in Gambas is in fact like the Java one, or any good 
object-oriented language. Not Visual-Basic !

So, there is no project global variables in Gambas like in VB. A global 
variable is global to a class or a module. And if you want to access a 
variable outside of its class or module, you must decalre it public.

To do the same thing as VB, declare your global variable in a module, and 
access it via the name of the module. For example,

Module MGlobal.module:
' Gambas module
PUBLIC BirthYear AS Integer
...

Module MMain.module (startup module):
' Gambas module
...
PUBLIC SUB Main()

  PRINT "BirthYear is"; MGlobal.BirthYear

END

Got it ? :-)
