Xs$Return

[Karl-Heinz]

i just recompiled a small VOGUI-App that uses Vulcan dlls.

"warning XS0219: The variable 'Xs$Return' is assigned but its value is never used"

what does 'Xs$Return' mean ?

Hi Karl-Heinz,

this message with Beta 5 should be gone.

Xs$Return is a compiler generated variable in assign methods, and this warning show up if your assign method returns something.

P.S. I had the same question, therefore I can answer this time

Hi Wolfgang

yes, it´s an typical VO assign.

> this message with Beta 5 should be gone

do you mean both builds: fox and public ?

at least the 2.0.0.5 public build throws this warning.

Hi Karl-Heinz,

accordingly to my ticket it should be ok, but I have just checked and my FoX build shows it also.

Karl Heinz, Wolfgang,

Do you see the problem with the following code ?

Code: Select all

CLASS Foo 
	PROTECT _bar AS STRING
ACCESS Bar AS STRING      
	RETURN _bar
ASSIGN Bar(cBar AS STRING) AS STRING      
	RETURN _bar := cBar
END CLASS

I only see warning 9032 (This entity type cannot return a value. Return value ignored.). The error about Xs$return should no longer be visible.

Hi Robert,

I see it wit the following code:

Code: Select all

assign ChangeHeaderDragDropCursor ( lSet as logic ) as logic pascal 

	_lChangeHeaderDragDropCursor := lSet
	
	return _lChangeHeaderDragDropCursor
