Proper Case Function

[JWise93]

I'm trying to create a function that produces an output of a string in "Proper Case." I have an attempt put together from other works I've found online, but am not having success. I'm not extremely familiar with SQL Anywhere and was hoping someone could lend a hand.

Here's what I have, but it errors at line 5.

CREATE FUNCTION Proper(in @Text long varchar)
RETURNS long varchar
AS
BEGIN
   declare @Reset   bit;
   declare @Ret   long varchar;
   declare @i   int;
   declare @c   char(1);

select @Reset = 1, @i=1, @Ret = '';

while (@i <= len(@Text))
    select @c= substring(@Text,@i,1),
        @Ret = @Ret + case when @Reset=1 then UPPER(@c) else LOWER(@c) end,
        @Reset = case when @c like '[a-zA-Z]' then 0 else 1 end,
        @i = @i +1
   return @Ret;
END;

Try this

CREATE FUNCTION Proper(in @Text long varchar)
RETURNS long varchar
BEGIN
   declare @Reset   bit;
   declare @Ret   long varchar;
   declare @i   int;
   declare @c   char(1);

   set @Reset = 1;
   set @i=1;
   set @Ret = '';

while (@i <= len(@Text)) loop
    set @c= substring(@Text,@i,1);
    set @Ret = @Ret + case when @Reset=1 then UPPER(@c) else LOWER(@c) end;
    set @Reset = case when @c like '[a-zA-Z]' then 0 else 1 end;
    set @i = @i +1;
end loop;

   return @Ret;
END;
