I'm getting an error message Test wouldn't be declared:
Code: Select all
EnableExplicit
Procedure Dummy()
Shared Test.POINT
EndProcedure

yes i can confirm this.
this works :
Code: Select all
EnableExplicit
Define Test.POINT
Procedure Dummy()
Shared Test
Debug Test\x
Debug Test\y
EndProcedure
Dummy()
Does this means that 'Shared' var should be defined once outside the procedure ? If so, maybe it's not a bug (?)

But this doesn't work.
So we are not able to share variables between procedures, without declaring it in the main program too.
Code: Select all
EnableExplicit
Procedure Dummy_1()
Shared Test.POINT
EndProcedure
Procedure Dummy_2()
Shared Test.POINT
EndProcedure
Dummy_1()
Dummy_2()

This was changed to have a consistent behaviour with shared LinkedLists and Arrays,
where they need to be defined in the main source first as well.

ok freak,
so, is this the good/clean syntax ?
Code: Select all
EnableExplicit
Define myPoint.POINT
Procedure Dummy1()
Shared myPoint
myPoint\x = 111
myPoint\y = 222
EndProcedure
Procedure Dummy2()
Shared myPoint
Debug myPoint\x
Debug myPoint\y
EndProcedure
Dummy1()
Dummy2()

Hmmmm, i'm just wondering...
And what the use to 'Shared' a variable previously defined as 'Global' ?
I think this should raise a debugger warning, no ?
Code: Select all
EnableExplicit
Global myPoint.POINT ; myPoint as 'Global'
Procedure Dummy1()
Shared myPoint ; This line should be removed - and it should raise a warning ! (?)
myPoint\x = 111
myPoint\y = 222
EndProcedure
Procedure Dummy2()
Debug myPoint\x
Debug myPoint\y
EndProcedure
Dummy1()
Dummy2()

It's no use, but it's not an error as well..

months ago we discussed in the german forum, whether the implementation
of Shared is similar to the basic idea of Shared Variables or not.
since PureBasic has a MainCode, where you also declare Globals,
its not that strange that Shared variables are accessable in this Maincode, too.
and with this, its consistent, that it has to be Defined in the Maincode,
when EnableExplicit is active.

the Variable is already Global, so it can be accessed in the Procedure.
if you try something like this:
you'll receive an Error.
so, if you keep in mind, to preDefine every Shared Variable in the Maincode,
you will be informed if some name conflict appears.
