Case structure et.al.

I have been having to jump between sql server and informix databases
and have gotten used to Case and Join syntax on the sql server side.  I
see the commands are valid under Informix 9.x that we have, but I can't
get any program to compile with Join or Case.
e.g.
select i.*, d.unitprice, d.prodname
    from invoice i join detail d on d.invoicenum = i.invoicenum

Left and right outer joins don't work either.

In the case of case:

select 'N' as TransCode,
	case shiploc.state
		when ('AB' ) then 'CAN'
		else 'USA'
	end as country,
	shiploc.store
from shiploc
into temp orders

This doesn't work either.
I tried enclosing that all in SQL ENDSQL and it didn't compile either.
