2375	Change default return value for SetError and SetExtended	MHz	Jpm	"Functions default to a 0 return value. Use of SetError or SetExtended sets a return value of 1 unless the return value parameter is used. The difference between 0 and 1 has always been ill behavior and always will be ill behavior until both return values use 0 by default.

People use all of the parameters to avoid the unpleasent default of 1 set by SetError and SetExtended. Anyone, which I have not seen, who uses the default of 1 needs to review their code as relying on 1 is not good especially since the help file states none as returned in 3.3.8.1 .

A 0 return by default has and always will be preferred and 1 is a usability bug.
{{{
$var = _Test()
MsgBox(0, 'Expect 1 returned', $var)

Func _Test()
	Return SetError(1)
EndFunc
}}}

Note that I have done a quick review of STD UDFs for compliance and I have submitted the bugs for 4 of them. So hopefully little to no affect will happen when the change is made."	Feature Request	closed	3.3.15.4	AutoIt		None	Completed
