GOTO statement syntax

[Sathish Rajagopalan]

Is GOTO statement supported in MySQL 5.0? I was trying the following simple procedure but was receiving compilation errors :

create procedure demo()
begin
declare var int;
label1:
begin
set @var = 0;
if @var = 0 then
select 'leaving';
goto label2;
end if;
set @var = 1;
end label1;
select @var;
label2:
begin
set @var = 2;
select @var;
end label2;
end

The compilation error occurs after goto at the start of "label2". I couldn't see any reference in the documentation. Is there something wrong with the syntax/usage. I am using 5.0.1-alpha-nt
